General Questions

These questions are not explicitly keyed to chapter topics; many require integration of several concepts.

Aluminum chloride reacts with phosphoric acid to give aluminum phosphate, AlPO₄, which is used industrially as the basis of adhesives, binders, and cements.

(a) Write a balanced equation for the reaction of aluminum chloride and phosphoric acid.

(b) If you begin with 152. g aluminum chloride and 3.00 L of 0.750-M phosphoric acid, calculate the mass of AlPO₄ that can be isolated.

(c) Use the solubility rules in Table 5.1 (◊p. 163) to predict the solubility of AlPO₄.
