What is the maximum pH of a saturated Al(OH)₃solution at 25°C?

Question

Quizplus · Accepted Answer

The correct answer is B because the maximum pH of a saturated Al(OH)3 solution at 25°C is 10.51. This is because Al(OH)3 is a weak base and its solubility is limited by the formation of the Al(OH)4- ion. The equilibrium constant for the dissolution of Al(OH)3 is 1.3 x 10-33, which means that the concentration of Al(OH)4- in a saturated solution is very low. The pH of a saturated Al(OH)3 solution is therefore determined by the hydrolysis of Al(OH)4-, which has a pKa of 10.51.
