Question

A constant electric current flows for 4 hours through two electrolytic cells connected in series. One contains $AgN{O}_3$ solution and second contains $CuC{l}_2$ solution. During this time, 4 grams of $Ag$ is deposited in the first cell. How many grams of Cu is deposited in the second cell?

• A. 2.176 g
• B. 0.176 g
• C. 1.176 g
• D. None of the above

Answer 1

The correct option is C 1.176 g

since $Cl$ & $Ag$ both are in series,

no. of eq. of $cl$= no. of eq. of $Ag$

No./ eq of $Ag=\frac{4gm}{107}$

& no. of eq.$cl=$ no. of eq. of $Ag=\frac{4}{107}$

eq. wt. of $cl=\frac{4}{107}\times \frac{1}{2}\times 63.5$

$eq.wtof\$Cl=1.176gm$
