C.C✓ Correct

D.D

Explanation

Equivalent weight of a base is defined as the ratio of molecular weight of the base by its acidity. MOLE & EQUIVALENT CONCEPT 68 Molecular weight Equivalent weight of base = Acidity The acidity of the base is defined as the number of replaceable hydroxide ions (OH) in one molecule of the base. Whereas basicity of acid is defined as the number of replaceable hydrogen ions ( H) in one molecule of the acid. Therefore, the assertion is true but the reason is false Comprehension Type questions Comprehension Often more than one reaction is required to change starting materials into the
