A) 20 ml of 0.1 M \[FeS{{O}_{4}}\]
B) 30 ml of 0.1 M \[FeS{{O}_{4}}\]
C) 40 ml of 0.1 M \[FeS{{O}_{4}}\]
D) 50 ml of 0.1 M \[FeS{{O}_{4}}\]
Correct Answer: D
Solution :
\[KMn{{O}_{4}}=\]Mohr salt \[\frac{{{M}_{1}}{{V}_{1}}}{{{n}_{1}}}=\frac{{{M}_{2}}{{V}_{2}}}{{{n}_{2}}}\]; \[\frac{0.1\times 10}{1}=\frac{{{M}_{2}}{{V}_{2}}}{5}\]; \[{{M}_{2}}{{V}_{2}}=5\].
