◦ soluble at low pH, insoluble in pH-neutral solution, and soluble at high pH
◦ insoluble at low pH, insoluble in pH-neutral solution, and soluble at high pH
◦ soluble at low pH, insoluble in pH-neutral solution, and insoluble at high pH
◦ insoluble at low pH, in pH-neutral solution, and at high pH

Question 2

What happens at low pH to aluminum hydroxide precipitate?
◦ Al forms.
◦ Al(OH)3 precipitate is still present.
