Analytical Chemistry Question 238
Question: The equivalent weight of $ Zn{{( OH )}_2} $ in the following reaction is equal to its, $
[Zn{{( OH )}_2}+( NO_3 )~Zn( OH )( NO_3 )+H_2O] $ [MH CET 1999]
Options:
A) $ \frac{Formula\ wt\text{.}}{2} $
B) $ \frac{Formula\ wt\text{.}}{1} $
C) $ 3\times formula\ wt\text{.} $
D) $ 2\times formula\ wt\text{.} $
Show Answer
Answer:
Correct Answer: B
Solution:
Equivalent weight of $ Zn{{(OH)}_2}=\frac{Molecularweight}{acidity}=\frac{M}{1} $ Acidity of $ Zn{{(OH)}_2}=1, $ only one $ OH $ is replaced.
