Answer : Cadmium sulfide (CdS) precipitate is formed.

Explanation :

When the sodium sulfide, is mixed with cadmium sulfate, then cadmium sulfide precipitate and sodium sulfate, is formed. The cadmium sulfide is insoluble in hot and cold water but sodium sulfate is soluble in water.

The balanced chemical reaction will be,

This reaction is an example of double displacement reaction in which the cation and anion of the two reactants exchange their places to give two new products.

This is a chemical reaction where the two clear solutions mixed to produce a bright yellow colored precipitate of cadmium sulfide.
