By passing a charge of 1930 through an aqueous solution of gold chloride, 1.314 g of gold was deposited. Find the oxidation state of gold. (Given atomic mass of Au =197 amu).

Text Solution

Verified by Experts

1.314 g of gold is deposited on passing charge=1930 C
197 g of gold is deposited on passing charge`=((1930C))/((1.314g))xx(197 g)=289353 C=(289353)/(96500)=3F`.
Oxidation state of gold is `=+3`
