Question:
You are presented with a white solid and told that due to careless labeling it is not clear if the substance is barium chloride, lead chloride, or zinc chloride. When you transfer the solid to a beaker and add water, the solid dissolves to give a clear solution. Next, a {eq}Na_2SO_4 {/eq} (aq) solution is added and a white precipitate forms. What is the identity of the unknown white solid?
A) {eq}BaCl_2 {/eq}
B) {eq}PbCl_2 {/eq}
C) {eq}ZnCl_2 {/eq}
D) {eq}PbCl {/eq}
E) {eq}BaCl {/eq}
General Solubility Rules:
The solubility of a compound in water can be determined by the ions present in the compound. The general solubility rules allow us to determine whether a compound will dissolve or precipitate in a solution.
