Question
The normality of orthophosphoric acid having purity of 70%by weight and specific gravity 1.54 is :The normality of orthophosphoric acid having purity of 70%by weight and specific gravity 1.54 is :
Options
A.11 N
B.22 N
C.33 N
D.44 N
Solution
70% by weight means Wt. of solute = 70 g
Wt of solution = 100g
∴ V∝ of solution =
We know that
N =
=
= 33 N
Wt of solution = 100g
∴ V∝ of solution =
We know that
N =
=
= 33 NCreate a free account to view solution
