0.759 g of a silver salt of a dibasic or...

0.759 g of a silver salt of a dibasic organic acid on ignition left 0.463 g metallic silver. The equivalent mass of the acid is :

A

70

B

108

C

60

D

50

Text Solution

Verified by Experts

The correct Answer is:
A
If E = eq.wt.of acid
W = weight of silver salt
w = weight of silver, then
`(W)/(E+107)=(omega)/(108), (0.759)/(E+107)=(0.463)/(108)rArr E = 70`.
