Answer to Question #95643 in Physical Chemistry for m

Question

Write a balanced overall reaction from these unbalanced half-reactions.

In⟶In3+

Cd2+⟶Cd

Answer 1

We know that,

$2Ln\to2Ln^{3+}+6e^-\ \ \ \ \ \ \ \ ........(1)$

Similarly,

$3Cd^{2+}+6e^-\to3Cd\ \ \ \ \ \ \ .........(2)$

Adding $(1)\ and\ (2)\$

We get,

$2Ln+3Cd^{2+}\to2Ln^{3+}+3Cd$
