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)42-. Use the lowest possible coefficients. Type the cation before the anion.)
overall equation:
_____ ________(aq) + _______NaOH(aq) gives _____ _________(aq)+_____ _________(s)
net ionic:
_____ ________(aq) + _____________(aq) gives _______ _________(s)
(b)What mass of precipitate forms when 109.0 mL of 0.680 M NaOH is added to 517 mL of a solution that contains 22.7 g aluminum sulfate per liter?
_______ g

Explanation / Answer

Al2(SO4)3 (aq) + 6NaOH (aq) gives 6Na2(SO4)3 (aq) + 2Al(OH)3(s)

Al2+ (aq) + 6OH- (aq) gives 2Al(OH)3 (s)

b) 1.93 grams Al(OH)3
