Question

2g of base X requires 100 ml of 0.4 N acid for complete neutralisation.the equivalent weight of base is?

Answer 1

Answer:

50

Explanation:

gram equivalent of base=gram equivalent of acid

given mass of base/equivalent mass of base =Normality ×volume

2/x =.4 ×100/1000

2/x =1/100

x = 50

Equivalent weight of base is 50 gm.

Answer 2

Answer:

50

Explanation:

GRAM EQUIVALENT WEIGHT OF BASE = NORMALITY ×VOLUME

: 0.4 ×100ML

0.4×100/1000L = 0.04L

EQUIVALENT OF ACID = EQUIVALENT WEIGHT OF BASE= 2/0.04
