Question

2 g of a base whose equivalent weight is 40 reacts with 3g of an acid. The equivalent weight of the acid is:

Answer 1

Explanation:
Given:Mass of base =2 gThe equivalent weight of base =40Mass of acid =3 gWe have to find the equivalent weight of acid.2 g of a base reacts with 3 g of acid.Let the equivalent weight of acid be E.Gram-equivalent is given by:Gram-equivalent = Mass Equivalent Mass Now since equivalents of all the reactants and products are equal.Gram-equivalent of base = Gram-equivalent of acidor, Mass of base Equivalent mass of base = Mass of acid Equivalent mass of acid Substituting all the values in equation (i), we get240=3EE=3×402=60Therefore, equivalent weight of acid is 60.Hence, the correct answer is 60.
