Question

Compound $PdC{l}_4.6H_{2}O$ is a hydrated complex; 1 m aqueous solution of it has freezing point 269.28 K. Assuming 100% ionization of complex, calculate the number of ions furnished by complex in the solution.

• A. 1
• B. 2
• C. 4

Answer 1

The correct option is B 2

$\Delta T=iKfm(273-269.28)=i\times 1.86\times 13.72=i\times 1.86i=2\alpha =\frac{i-1}{n-1};(\alpha =100\%=1)1=\frac{2-1}{n-1}\Rightarrow n=2$
