Acids and Bases
An acid is any substance whose aqueous solution is characterized by a sour taste, the ability to turn blue litmus red, and the ability to react with bases and certain metals to form salts. A Base is any substance whose aqueous solution is characterized by a bitter taste, a slippery feel, the ability to turn red litmus blue, and the ability to react with acids to form salts. Questions about the acidity and alkalinity of solutions and different types of acids and bases are found n our Acids and Bases category.

What is the valency of sulphuric acid?
Ah, sulfuric acid is a special one! It has a valency of 2, which means it can combine with other elements in a very balanced way. Just like when you mix different colors on your palette to create a beautiful painting, sulfuric acid combines with other elements to form different compounds that have their own unique properties. Isn't that just lovely?
Most rain water is mildly acidic, due to dissolved CO2 and SO2 gases emanating from automobiles and other combustion sources. This phenomenon is known as acid rain. The mild acid is what turns copper roofs green, for example.
The H2SO4 plus 2NaOH too Na2SO4 plus 2H2O what is this type of reaction?
This is a double displacement reaction, also known as a double replacement reaction, where the positive and negative ions of two ionic compounds switch places to form two new compounds.
NO!!!!
Fluorine is an elemental gas in the HALOGEN Group.
The word 'halogen' is from Latin and means 'salt maker'. So when fluorine is combined with a Group (I) or (II) metal (Alkali/Alkali Earth Metal) ot forms a salt.
e.g.
2Na(s) + F^(2)(g) = 2NaF(s) ( The chemical salt).
Why does zinc hydroxide dissolve in excess dilute sodium hydroxide?
Zinc hydroxide dissolves in excess dilute sodium hydroxide because it forms a complex ion, [Zn(OH)4]^2-, which is soluble in aqueous solution. This complex ion helps stabilize the zinc hydroxide and prevents it from precipitating out of solution.
What minerals will fizz in contact with hydrochloride acid?
Minerals containing carbonate ions, such as calcite (calcium carbonate) and dolomite (magnesium carbonate), will fizz in contact with hydrochloric acid due to the release of carbon dioxide gas. This reaction is a common test to identify carbonate minerals.
What is the coefficient for H20 when the following equation is balanced K plus H20 plus KOH plus H2?
2K(s) + 2H2O(l) = 2KOH(aq) + H2(g)
The eq'n is balanced.
The coefficients ( molar ratios) in order of the reation eq'n are 2:2:::2:1
What is the symbol equation of gold and sulfuric acid?
The symbol equation for the reaction between gold and sulfuric acid is Au + H2SO4 → Au2(SO4)3 + H2. In this reaction, gold (Au) reacts with sulfuric acid (H2SO4) to form gold sulfate (Au2(SO4)3) and hydrogen gas (H2). The balanced equation shows the stoichiometry of the reaction, indicating that one mole of gold reacts with three moles of sulfuric acid to produce one mole of gold sulfate and one mole of hydrogen gas.
How do you neutralize a villain visitor in shop empire 2?
Oh, darling, in Shop Empire 2, to neutralize a villain visitor, you simply click on them and select the "Call Security" option. Then sit back, sip your tea, and watch as those troublemakers get escorted out faster than you can say "cha-ching!" Just remember, the customer may always be right, but not when they're causing chaos in your shop!
How do you convert gallons of 50 percent caustic soda into dry tons of caustic soda?
To convert gallons of 50% caustic soda into dry tons, you first need to determine the weight of the actual caustic soda in the solution. Since the solution is 50% caustic soda, half of the weight of the solution is caustic soda. Next, you need to convert the weight of caustic soda from gallons to pounds using the density of caustic soda. Finally, you can convert the weight in pounds to dry tons by dividing by 2000 (since there are 2000 pounds in a ton).
Is zinc sulphate a acid or base?
Zinc sulfate is neither an acid nor a base. It is a salt that is formed by the reaction of zinc oxide with sulfuric acid. When dissolved in water, zinc sulfate dissociates into zinc ions and sulfate ions.
Definitely ACIDIC .
It is the corresponding acid to hydrochlorice acid.
The halogen acids are
HF = hydrofluoric acid
HCl = Hydrochloric Acid
HBr = hydrobromic acid
HI = hydroiodic acid.

What color is the universal indicator in an alkali?
The universal indicator in an alkali solution typically turns a dark blue or purple color. This color change is due to the presence of hydroxide ions in the solution, which indicates a high pH level. The universal indicator is a mixture of different dyes that change color based on the pH of the solution, with blue or purple indicating a strong alkali.
Any acid that contains two(2) hydrogen ions.
Sulphuric and Sulphurous acids are bi-protic. (H2SO4/H2SO3)
However, hydrochloric and nitric acids are mono-protic. (HCl/ HNO3)
Phosphoric acid is tri-protic. (H3PO4)
The nomenclature (naming system) is based on Latin/
Mono = 1
Bi = 2
Tri - 3
Protic = from 'proton'.;
What is the result of CO3 2- plus H2SO4?
Ah, what a happy little chemical reaction we have here! When CO3 2- (carbonate ion) reacts with H2SO4 (sulfuric acid), it forms CO2 (carbon dioxide) gas, H2O (water), and SO4 2- (sulfate ion). It's like nature's own magical transformation, creating new substances with each brushstroke of the reaction.
Sodium hypochlorite and sulfuric acid?
Sodium hypochlorite is a chemical compound with the formula NaClO, commonly known as bleach. Sulfuric acid, on the other hand, is a strong mineral acid with the formula H2SO4. When sodium hypochlorite reacts with sulfuric acid, it can produce chlorine gas, which is toxic and corrosive. This reaction is exothermic and should be carried out with caution in a well-ventilated area.
Oh, dude, HCO3- is a bicarbonate ion, which can act as both an acid and a base depending on the context. It can accept a proton and act as a base, or it can donate a proton and act as an acid. So, like, it's a bit of a flip-flopper in the world of chemistry.
How do you prepare 1M sulfuric acid from concentrated sulfuric acid?
To prepare 1M sulphuric acid from concentrated sulphuric acid:
- First consider the molecular weight of H2SO4 = 98 g/mol, so you have to add 98g of conc. acid and make up to 1 liter of water (as pointed out at the 4thpoint).
- Considering that acid is a liquid, you should also consider density:
where density = mass/volume, which is said on the bottle to be (about) 1.84 g/mL,
so then you have: volume = 98g / 1.84(g/mL) = 53.2 mL
- Now you have to consider the acid purity, usually 98% then you have to do this:
53.2 mL if the acid were 100% pure convert in mL given with the purity of 98%, so 100% x 53.2 mL / 98% = 54.3 mL of (98%) concentrated acid.
- Finally CAREFULLY add this 54.3 mL (or 98 g, cf. first point) to about 0.9 L dist. water while continuously stirring (evolving heat!), and after that fill it up to 1.00 L with also dist. water.
Never reverse this: DO NOT add water to concentrated fluids!
Why Adding concentrated acid to water is exothermic?
Well, honey, when you add concentrated acid to water, it's like mixing fire and gasoline - things are gonna heat up real quick! The reaction between the acid and water releases energy in the form of heat, making it exothermic. So, remember, always add acid to water, unless you want a fiery science experiment on your hands!
How do you prepare 0.25 N HCL solution?
Well, preparing a 0.25 N HCl solution is as easy as painting a happy little tree. Simply measure out the correct amount of concentrated hydrochloric acid and dilute it with water until you reach the desired volume. Remember to always add acid to water, not the other way around, to stay safe and create a beautiful solution.
The chemical formula 2H2SO4 represents two molecules of sulfuric acid. In this formula, "2" indicates the number of molecules, "H" represents hydrogen, and "SO4" represents the sulfate ion. Therefore, 2H2SO4 signifies two molecules of sulfuric acid, each consisting of two hydrogen atoms and one sulfate ion.
Can acids be made safe by heating them?
NO!!!!
If you heat acids , any thing else, the molecules will vapourise , nad move into the air, where they can be breathed in.
Two ways to make an acid safer are
-
Dilution with water.
-
neutralise with an alkali.,
Is NH3 a bronsted acid or base?
Well, darling, NH3 is a bronsted base. It's like the friend who always has your back and is ready to donate a proton at a moment's notice. So, if you're looking for some basic chemistry knowledge, NH3 is your go-to base buddy.
Is borax and boric acid the same?
No, borax and boric acid are not the same. Borax is a naturally occurring mineral (sodium borate), while boric acid is a refined compound derived from borax. Both have different chemical compositions and uses.
