Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Stoichiometry
Stoichiometry is the calculation of reactants and products in chemical reactions. It involves using balanced chemical equations to determine the relationships between the amounts of substances consumed and produced. In this case, stoichiometry will help us find the moles of hydrochloric acid needed to react with aluminum hydroxide.

Stoichiometry Concept
Molarity
Molarity (M) is a measure of concentration defined as the number of moles of solute per liter of solution. It is crucial for determining how much of a solution is needed to achieve a desired reaction. In this question, the molarity of hydrochloric acid will be used to calculate the volume required for the reaction with aluminum hydroxide.

Balanced Chemical Equation
A balanced chemical equation represents a chemical reaction with equal numbers of each type of atom on both sides of the equation. It provides the mole ratios needed for stoichiometric calculations. For this problem, the balanced equation between hydrochloric acid and aluminum hydroxide will indicate how many moles of HCl are required to completely react with the given mass of Al(OH)3.

Textbook Question
A solution contains one or more of the following ions: Ag+ , Ca2+ , and Cu2+ . When you add sodium chloride to the solution, no precipitate forms. When you add sodium sulfate to the solution, a white precipitate forms. You filter off the precipitate and add sodium carbonate to the remaining solution, producing another precipitate. Write net ionic equations for the formation of each of the precipitates observed.
