Chemistry - Ionic Equilibrium Question with Solution | TestHub

Ostwald’s dilution formula is${\mathrm{\alpha }}^2=\mathrm{K}(1-\mathrm{\alpha })/\mathrm{C}$but for weak electrolyte$\mathrm{\alpha }$is very small. So that$(1-\mathrm{\alpha })$is neglected for weak electrolytes. So for weak electrolyte the dilution formula is$\mathrm{\alpha }=\sqrt{\frac{\mathrm{K}}{\mathrm{C}}}$.
