Chemistry - Ionic Equilibrium Question with Solution | TestHub

Given ${\mathrm{K}}_a=1.00\times 10^{-5},\mathrm{C}=0.100$ mol for a weak electrolyte, degree of dissociation $\propto =\sqrt{\frac{{\mathrm{K}}_a}{\mathrm{C}}}=\sqrt{\frac{1\times 10^{-5}}{0.100}}=10^{-2}=1\%$ Related Theory In any acid-base reaction, the equilibrium will favour the reaction that moves the proton to the stronger base. This equilibrium constant is referred to as the ion-product constant for water, Kw. In pure water, some molecules act as bases and some as acids.
