Chemistry - Ionic Equilibrium Question with Solution | TestHub

pH of 9.2 – 9.3 is produced by a basic buffer obtained by mixing a weak base (like$\mathrm{N}{\mathrm{H}}_3$) with its salt formed by the reaction of$\mathrm{N}{\mathrm{H}}_3$with strong acid$(\mathrm{N}{\mathrm{H}}_3+\mathrm{H}\mathrm{C}\mathrm{l}\to \mathrm{N}{\mathrm{H}}_4\mathrm{C}\mathrm{l})$.
