Question

2g of a base whose equivalent wt is40 react with 3g of an acid the eq.wt of the acid is?

Answer 1

Answer:

Explanation:

1. For a reaction :

aA + bB → cC

Gram equivalence of A = Gram equivalence of B = Gram equivalence of C

2. So, Gram equivalence of Acid = Gram equivalence of Base

Given massEquivalent massof Acid = Given massEquivalent massof base3x=240x= 3×402=60

________________________

No. of gram equivalents of BASE = No. of gram equivalents of ACID.

Therefore,

2/40 = 3/x

x = 3.20

x = 60.

Hence the equivalent weight of the substance is 60.
