Calculate the extent of hydrolysis of \( 0.005 \mathrm{M} \mathrm{K}_{2} \mathrm{CrO}_{4} \). \(...

Calculate the extent of hydrolysis of \( 0.005 \mathrm{M} \mathrm{K}_{2} \mathrm{CrO}_{4} \). \( \left[\mathrm{K}_{2}=3.1 \times 10^{-7}\right. \) for \( \left.\mathrm{H}_{2} \mathrm{CrO}_{4}\right] \) (It is essentially strong for first ionization).
