(a) Interpretation: Theappropriate curve from the given data should be drawn and from the given graph maximum mass of precipitate that can be obtained should be determined. Concept introduction: A double displacement reaction refers to a chemical reaction in which two compounds react in such a way that the positive and the negative ions of the two reactant molecules switch their places so as to form new products or compounds. A precipitation reaction is a kind of chemical reaction in which an insoluble salt is formed when two solutions that contain soluble salts are made to react with each other.

Solution Summary: The author explains the stoichiometric proportions of a double displacement reaction and the precipitation reaction.
Definition Definition Transformation of a chemical species into another chemical species. A chemical reaction consists of breaking existing bonds and forming new ones by changing the position of electrons. These reactions are best explained using a chemical equation.

Interpretation Introduction
(b)
Interpretation:
Thereason for the maximum amount of precipitate which is obtained due to the presence of the reactants in their stoichiometric proportions needs to be determined.
Concept introduction:
A double displacement reaction refers to a chemical reaction in which two compounds react in such a way that the positive and the negative ions of the two reactant molecules switch their places so as to form new products or compounds. A precipitation reaction is a kind of chemical reaction in which an insoluble salt is formed when two solutions that contain soluble salts are made to react with each other.
Interpretation Introduction
(c)
Interpretation:
The relation between stoichiometric proportions determined in part (b) and the balanced chemical equation needs to be determined.
