Question

Aluminum sulfate, known as cake alum, has a remarkably wide range of uses, from dyeing leather and cloth to purifying sewage. In aqueous solution, it reacts with base to form a white precipitate.

(a) Write balanced total and net ionic equations for its reaction with aqueous NaOH. (Type your answer using the format (NH4)2CO3 for (NH₄)₂CO₃, [NH4]+ for NH₄⁺, and [Ni(CN)4]2- for Ni(CN)₄^2-. Use the lowest possible coefficients. Type the cation before the anion.)
