Statement 1: The molecular weight of any substance is unique but the equivalent weight is not unique.
Statement 2: Equivalent weight of any substance depends on its nature in the chemical reaction concerned.
Options:
Answer:
A
Solution:
I is correct: a substance has one fixed molecular weight, but its equivalent weight varies with the reaction (e.g. KMnO₄ has E = M/5 in acid, M/3 in neutral, M/1 in strong base). II is correct and is exactly the reason: the n-factor, and hence E, depends on the role the substance plays in the particular reaction. II explains I, so (a).
