Concept explainers
Interpretation : The solubility of lead chromate in grams/L at 25°C needs to be determined.
Concept Introduction : The solubility product can be defined as the product of the equilibrium concentrations of the ions in a saturated solution of a salt. In the expression of solubility product each concentration is raised to the power of their coefficient of ion as given in the balanced equation. For example;
The solubility expression will be:
The product of the concentrations of the ions at any moment in time for the given salt is called as ion product that is represented as
Answer to Problem 53A
Explanation of Solution
Given information:Chromate ion is used as a qualitative test for lead (II) ions as it forms bright yellow precipitate of lead chromate.
Thus, the
Molar mass of
Calculate the solubility in g/L:
Thus, the solubility is
