Chemistry - Ionic Equilibrium Question with Solution | TestHub

$\mathrm{N}{\mathrm{H}}_4\mathrm{N}{\mathrm{O}}_3$is salt of very weak base and very strong acid hence it will produce most acidic solution on hydrolysis. Aqueous solutions of$\mathrm{C}\mathrm{u}\mathrm{S}{\mathrm{O}}_4$and$\mathrm{A}\mathrm{l}\mathrm{C}{\mathrm{l}}_3$are also acidic.
