Answer:

Al(OH)3(s) , aluminum hydroxide dissolves in water and acts a base. It is a common ingredient in antacid products. The overall solution process produces three hydoxide ions and an aluminum ion. The dissolving process occurs in a series of 3 steps with a hydroxide ion released in each step. Al(OH)3(s) + H2O(l) -----> Al3+ (aq) + 3 OH1- (aq) <--- total process Al(OH)3(s) + H2O(l) -----> Al(OH)2+ (aq) + 1 OH1- (aq)<--- step 1 Al(OH)2+ (aq) + H2O(l) -----> Al(OH)2+(aq) + 1 OH1- (aq)<--- step 2 Al(OH)2+(aq) + H2O(l) -----> Al3+ (aq) + 1 OH1- (aq)<--- step 3
