Acids burn and irritate the skin.
They change;
- Litmus from blue to red
- Phenolphthalein from pink to colourless
- Methyl orange and methyl red from yellow to red
They react with;
- Metals to give hydrogen gas
- Carbonates to give CO2
- Alkali to give a salt and water
- Metal oxides to give a salt and water
All have hydrogen in their formulas and they do need water or moisture to behave as an acid.
Properties of chemical acids:
- they have a characteristically sour taste
- they are indicated when blue litmus paper turns red
- they have a pH less than 7
- they form electrolytes in water
- they produce H2 (hydrogen gas) when they react with certain metals
- they are chemical proton donors
- they combine with bases to form water and various salts
- they can be corrosive in high concentrations
- they can cause burns to organic tissues
the answer is hahahaha, because lol could take gnr and lmfao was singing horribly!

Extensive or intensive?
Neither. Benzoic acid is... benzoic acid. Intensive and extensive are properties are characteristics of elements and compounds such as color, density, odor, conductivity, etc. To say benzoic acid is extensive or benzoic acid is intensive doesn't make sense.
Does citric acid turn water blue?
No. Citric acid is used in many dyes requiring an acid, and in many foods for its sour taste, but it does not color anything. Here is a full description of the properties: https://en.wikipedia.org/wiki/Citric_acid
Word equation for neutralisation?
The word equation for neutralization is typically represented as "acid + base → salt + water." This equation shows the reaction between an acid and a base resulting in the formation of a salt and water. In this chemical reaction, the acidic properties of the acid are neutralized by the basic properties of the base, leading to the formation of a neutral salt.
Compare physical and chemical properties?
A chemical property is the substance's response to other substances, resulting in a new substance. A physical property is something like a substance's lustre, melting point, boiling point, colour, or density, to name a few. Examples of chemical properties are: combustibility and reaction to acid.
What are Examples of chemical properties?
Reactivity with water, oxidation, flammability
Do these four properties describe an acid or a base?
Can you please provide the four properties for me to determine if they describe an acid or a base?
Is borax an acid?
No, borax is not an acid. It is a salt of boric acid, which has basic properties.
acid is acid right means red?
Acid does not always mean red. The color of an acid depends on its specific chemical properties and characteristics. Acids can come in various colors, and their color is not directly related to their acidic properties.
Is vinagar an acid or a alkali?
Vinegar is an acid. It is primarily composed of acetic acid, which gives it its sour taste and acidic properties.
Why does acid rune your skin?
Acid RUINS your skin because of the dangerous chemical properties.
The particle responsible for acid properties in water is?
The particle responsible for acid properties in water is the hydrogen ion (H+). When an acid is dissolved in water, it releases H+ ions, which give the solution acidic properties by increasing the concentration of hydronium ions (H3O+).
When you combine and acid an base what is formed?
When an acid and a base are combined, they react to form water and a salt. This reaction is known as neutralization, where the acidic properties of the acid and the basic properties of the base are neutralized by each other.
What is it called when a acid reacts with an alkali?
The reaction between an acid and an alkali is called neutralization. In this reaction, the acidic properties of the acid are neutralized by the basic properties of the alkali, resulting in the formation of water and a salt.
Is vinegar and acid or base?
Vinegar is an acid. It is primarily composed of acetic acid, which gives it its sour taste and acidic properties.
What acid is called as red acid?
Sulfuric acid is commonly referred to as "red acid" due to its corrosive and potentially dangerous properties.
What are the database properties?
ACID (Atomicity, Consistency, Isolation, Durability) is a set of properties that guarantee the database.
What happens to the corrosive properties of an acid and a base after they neutralise each other?
These corrosive properties disappear.
