When solutions of aluminum sulfate and sodium hydroxide are mixed, white gelatinous precipitate forms.

(a) Write a balanced net ionic equation for the reaction

(b) What is the mass of the precipitate when 2.76 g aluminum sulfate in 125 mL of solution is combined with 85.0 mL of 0.2500 M NaOH?

(c) What is the molarity of the ion in excess? (Ignore spectator ions and assume that volumes are additive)
