Q. Barium ions, $CN ^{-}$and $Co ^{2+}$ form an ionic complex. If that is supposed to be $75 \%$ ionised in water with van't Hoff factor $(i)$ equal to four, then the coordination numbers of $Co ^{2+}$ in the complex can be:

Solutions

Solution:

$\alpha=\frac{i-1}{x-1}=\frac{3}{4}=\frac{4-1}{x-1}$
$\therefore x=5$
$\therefore $ Complex is $Ba _{3}\left[ Co ( CN )_{5}\right]_{2}$
