When acid A is added to base B, C is produced along with a large amount of heat. C is used in manufacture of plaster of Paris. Identify A, B and C.

Correct option is D

The Correct answer is A-Sulphuric acid; B-Lime water; C-Calcium sulphate.
• When sulphuric acid (H2SO4) is added to lime water (Ca(OH)2), calcium sulphate (CaSO4) is produced along with a large amount of heat.
• This reaction is a neutralization reaction, which is a type of chemical reaction that occurs when an acid and a base react to form salt and water.
• The chemical equation for the reaction is:
H2SO4 + Ca(OH)2 CaSO4 + 2H2O
• In this equation, sulphuric acid (H2SO4) is the acid, lime water (Ca(OH)2 is the base, calcium sulphate (CaSO4) is the salt, and water (H2O) is the product.
• Calcium sulphate is used in the manufacture of plaster of Paris. When calcium sulphate is heated to a high temperature, it loses some of its water molecules and becomes a power called plaster of Paris.
• When the plaster of Paris is mixed with water, it rehydrates and forms a hard solid. This property of the plaster of Paris makes it useful for making casts, moulds, and other objects.
