Redox Reactions And Electrochemistry Ques 304
Question: A certain quantity of electricity is passed through an aqueous solution of $ AgNO_3 $ and cupric salt solution connected in series. The amount of $ Ag $ deposited is $ 1.08,gm $ , the amount of copper deposited is (atomic weight of Cu = 63.5; Ag = 108) [EAMCET 1986]
Options:
A) 0.6454 g
B) 6.354 g
C) 0.3177 g
D) 3.177 g
Show Answer
Answer:
Correct Answer: C
Solution:
$ \frac{Wt\text{.},of\ Cu}{Wt\text{.},of,Ag}=\frac{Eq\text{. }wt\text{.},of,Cu}{Eq\text{.},wt\text{.},of,Ag} $ ; $ \frac{Wt\text{.}ofCu}{1.08}=\frac{63.5/2}{108} $ Wt. of $ Cu=0.3177gm $ .
