Monobasic acids can donate only one proton (H+) per molecule in a reaction, while dibasic acids can donate two protons per molecule. This means that dibasic acids have double the acidic strength compared to monobasic acids.

Sulfuric acid (H2SO4), phosphoric acid (H3PO4), and carbonic acid (H2CO3) are examples of dibasic acids. These acids have two ionizable hydrogen atoms, meaning they can donate two protons per molecule when dissolved in water.

Dibasic acid is an acid that can donate two protons (H+) per molecule in a chemical reaction, while diprotic acid is an acid that can release two protons (H+) in solution. The key difference is that dibasic acid refers to the number of acidic groups in the molecule, while diprotic acid refers to the number of protons that can be donated.

To prepare a decinormal solution of a dibasic acid with a molecular weight of 200 g/mol, you would need 4.0 grams of the acid dissolved in 100 mL of water. This is because a decinormal solution has a concentration of 0.1 equivalent per liter, and since a dibasic acid donates 2 equivalents of protons per molecule, you would need twice the gram equivalent weight of the acid.

Yes, dibasic acids have two hydrogen ions to donate in an acid-base reaction, making them more acidic than monobasic acids that only have one hydrogen ion to donate.

The basicity of an acid refers to the number of hydrogen ions (H+) that it can donate when it dissociates in a solution. A monobasic acid donates one H+, a dibasic acid donates two H+, and so on. It is a measure of the acid's strength and is related to its ability to neutralize bases.

To prove that sulfuric acid is dibasic, you need to observe that it can donate two protons (H+) per molecule in solution. This is evident in its chemical formula, H2SO4, which indicates it has two ionizable hydrogen atoms that can dissociate in water. This characteristic allows sulfuric acid to form two series of salts, known as normal sulfates and acid sulfates.

H3PO3 is a dibasic acid because it has two replaceable hydrogen ions that can be ionized in a solution to form hydrogen ions (H+) and a phosphate ion (H2PO3-). This allows it to donate two protons and form two acidic solutions.

Titration...after neutralizations with a base, molarity calculations are done and you will find that one mole sulphuric acid needed 2 moles of the given base in order for a complete reaction to occur.
Can anyone give the method and calculations to this titration experiment please? and can anyone give a method and calculations to a gas collection experiment to prove that sulphuric acid is dibasic?
... I personally reckon that this is your AS chemistry planning exercise lol
Do it yourself!!!

KH2PO4 is monobasic because it contains one replaceable hydrogen ion for each molecule of the compound. K2HPO4 is dibasic because it contains two replaceable hydrogen ions for each molecule of the compound. The number of replaceable hydrogen ions determines whether a compound is classified as monobasic, dibasic, tribasic, etc.

Hypophosphorous acid (H3PO2) behaves as a monobasic acid. It has one ionizable hydrogen atom which can donate one proton in a neutralization reaction.
2 answers
A dibasic acid contains two hydrogen atoms that can be ionized to form two acidic hydrogen ions (H+). A monobasic acid contains only one hydrogen atom that can be ionized to form one acidic hydrogen ion (H+). This difference can be identified by the number of replaceable hydrogen ions in the acid molecule.

Well, honey, HF is dibasic because it can donate two protons when it dissolves in water. It's a feisty little compound that loves to show off its acidic side by releasing those protons like it's nobody's business. So, yeah, HF is dibasic because it's just that extra when it comes to being acidic.

Dipotassium phosphate (K2HPO4) - also phosphoric acid, dipotassium salt; dipotassium hydrogen orthophosphate; potassium phosphate, dibasic - is a highly water-soluble salt which is often used as a fertilizer, food additive and buffering agent. It is a common source of phosphorus and potassium.
The pH of a dipotassium phosphate solution is almost neutral. It is formed by the stoichiometric neutralization of phosphoric acid with potassium hydroxide:
H3PO4 + 2 KOH → K2HPO4 + 2 H2O
It reacts with phosphoric acid to generate monopotassium phosphate:
K2HPO4 + H3PO4 → 2 KH2PO4

Dibasic bases have two ionizable hydrogen atoms, making them capable of accepting two protons in chemical reactions. This property allows them to act as strong bases, reacting with acids to form salts and water. Dibasic bases are commonly used in organic synthesis, as catalysts, and in the production of pharmaceuticals and polymers.

Dibasic salts are salts that contain two replaceable hydrogen ions per molecule. These salts are capable of forming two types of ions when dissolved in water, with two acidic protons that can be neutralized by a base. Examples of dibasic salts include calcium carbonate (CaCO3) and magnesium sulfate (MgSO4).

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'.;

An alkyd is polyester made by reacting a polyol with a dibasic acid. An oil-modified alkyd isan oil-modified polyester made from oil and polyol and a dibasic acid. OILs
The oils are triglyceride oils. Three fatty acid groups react with glycerine to form a triglyceride. There are 18 carbon atoms in the fatty acid molecule. The oils can be drying oils or non‑drying oils. Some drying oils are Tung, dehydrated castor oil, linseed, safflower, soybean oil and fish oil. Some non‑drying oils are palm, coconut and cottonseed oil.

Drying Non‑ drying
Tung Coconut
Dehydrated castor oil Palm
Linseed Cotton seed
Safflower

Polyols
The following polyols can be used to make alkyds Glycerine, pentaerythritol,trimethylol Propane and trimethylol ethane.
Dibasic acids
The most commonly used acid is phthalic anhydride. Isophthalic acid can also be used. Other dibasic acids are adipic acid, maleic anhydride and fumaric acid.
Mole Ratio of Phthalic to Glycerine
The mole ratio of phthalic to glycerine is (3) to (2.4)
This
Ratio is use when making 50% oil length alkyds. The same ratio is used
When making alkyds over 50% oil. For short oil alkyds you increase the mole ratio of glycerine to control viscosity and prevent gellation.

Basicity refers to the ability of a substance to donate a pair of electrons in a chemical reaction. The more readily a substance can donate electrons, the higher its basicity. This property is especially important in the context of acids and bases, where basicity determines the ability of a substance to neutralize an acid.

Dibasic potassium phosphate buffer is a solution commonly used in laboratories to control the pH of a reaction or a sample. It consists of a mixture of potassium dihydrogen phosphate (KH2PO4) and dipotassium hydrogen phosphate (K2HPO4) in specific ratios to maintain a stable pH. This buffer is especially useful in biochemical and molecular biology experiments.
