'Sulphuric acid is a dibasic acid.'write two equations to justify this statement and name the reaction products in two cases.?

Question

Answer

See the formula of sulphuric acid is H2SO4.
hydrogen atoms = 2
nd di means 2 .

so it is dibasic

Hope this helps...

Answer

Sulphuric acid as a dibasic acid

Sulphuric acid is a dibasic acid because it has two acidic hydrogen atoms that can be ionized in water to form two hydrogen ions (H+). This can be represented by the following two equations:

Equation 1:

H2SO4 + H2O → HSO4- + H3O+

Here, sulphuric acid (H2SO4) reacts with water (H2O)

This reaction results in the formation of a hydrogen ion (H+) and a bisulphate ion (HSO4-)

The hydrogen ion (H+) can further react with water to form a hydronium ion (H3O+)

Equation 2:

HSO4- + H2O → SO42- + H3O+

In this equation, the bisulphate ion (HSO4-) reacts with water (H2O)

The reaction results in the formation of a hydrogen ion (H+) and a sulphate ion (SO42-)

The hydrogen ion (H+) can again react with water to form a hydronium ion (H3O+)

Thus, sulphuric acid is a dibasic acid because it can donate two protons (H+) in solution. This property of sulphuric acid makes it an important industrial chemical for a wide range of applications.

Reaction products in two cases

When sulphuric acid reacts with different substances, it can form different products. Here are two examples:

Reaction with sodium hydroxide:

H2SO4 + 2NaOH → Na2SO4 + 2H2O

In this equation, sulphuric acid (H2SO4) reacts with sodium hydroxide (NaOH)

The reaction results in the formation of sodium sulphate (Na2SO4) and water (H2O)

Reaction with calcium carbonate:

H2SO4 + CaCO3 → CaSO4 + CO2 + H2O

In this equation, sulphuric acid (H2SO4) reacts with calcium carbonate (CaCO3)

The reaction results in the formation of calcium sulphate (CaSO4), carbon dioxide (CO2), and water (H2O)

These reactions illustrate how sulphuric acid can react with different substances to form different products. The versatility of sulphuric acid makes it an important industrial chemical that is used in many applications, including the production of fertilizers, detergents, and other chemicals.
