Law of Equivalence MCQ - Practice Questions with Answers

Laws of Equivalence
According to the law of equivalence, for each and every reactant and product, 
Equivalents of each reactant reacted = Equivalents of each product formed.

Example,
Suppose the reaction is taking place as follows: 
 

According to the law of equivalence, 

Equivalents of P reacted = Equivalents of Q reacted = Equivalents of R produced = Equivalents of S produced 

Equivalents of any substance = (Weight of substance (in g)) / (Equivalent weight)
= Normality (N) x Volume (V) (In litre) 
Normality (N) = n-Factor x Molarity (M) 

Law of Equivalence finds great importance in Acid base Neutralisation Reactions as well as Redox Titrations.

Here we shall be mainly covering the Acid Base neutralisation reactions in detail.
