The equivalent weight of Zn(OH)2\mathrm{Zn}{\left( {\mathrm{OH}} \right)_2} in the following reaction is equal to its,
Zn(OH)2+HNO3→Zn(OH)(NO3)+H2O\mathrm{Zn}{\left( {\mathrm{OH}} \right)_2} + \mathrm{HN}{\mathrm{O}_3} \to \mathrm{Zn}\left( {\mathrm{OH}} \right)\left( {\mathrm{N}{\mathrm{O}_3}} \right) + {\mathrm{H}_2}\mathrm{O}:
View answer and explanation
Correct option: A
Formula  wt.1\frac{{\mathrm{Formula}\;\mathrm{wt}\mathrm{.}}}{1}
Option A (Formula wt./1) is correct because in this reaction, Zn(OH)2Zn(OH)_2 reacts with one equivalent of HNO3HNO_3, so its equivalent weight is its formula weight divided by 1.
