MCQ
If $M$ is the molecular weight of $KMn{O_4}$, its equivalent weight will be when it is converted into ${K_2}Mn{O_4}$
- ✓$M$
- B$M/3$
- C$M/5$
- D$M/7$
✓
Answer
Correct option: A.
$M$
a
(a)${\rm{Equivalent }}\,{\rm{wt}}{\rm{. }} = {\rm{ }}\frac{{{\rm{molecular}}\,\,{\rm{wt}}{\rm{.}}}}{{{\rm{total no}}{\rm{. of }}{e^--}\,{\rm{gained or lost}}}}$$ = \frac{M}{1} = M$
(a)${\rm{Equivalent }}\,{\rm{wt}}{\rm{. }} = {\rm{ }}\frac{{{\rm{molecular}}\,\,{\rm{wt}}{\rm{.}}}}{{{\rm{total no}}{\rm{. of }}{e^--}\,{\rm{gained or lost}}}}$$ = \frac{M}{1} = M$
