The answer to this question is E, ZnF subscript 2. When a student mixes equal volumes of 1.0 M solutions of tin(II) chloride and copper(II) sulfate and observes that no precipitate forms. Then the student mixes equal volumes of 1.0 M solutions of zinc(II) sulfate and tin(II) fluoride and observes the formation of a precipitate.

This means that the precipitate that the student uses is ZnF subscript 2. The definition of the word precipitate in chemistry is the cause of a substance to be deposited in solid form from a solution. You must use the formula to discover the precipitate.
