Does a precipitate form when a solution of sodium acetate and a solution of ammonium sulfate are mixed together?

Answer;

No, a precipitate does not form

Explanation; Precipitation involves mixing or combining solutions that contain soluble ionic compounds to form an insoluble ionic compound by a reaction. Sodium acetate and ammonium sulfate are both soluble ionic compounds, which implies that they exist as ions in aqueous solution. When they combine they form NH4CH3COOH and sodium sulfate, Na2SO4, which are both soluble salts, as all salts of ammonium and sodium are soluble. Both ammonium acetate and sodium sulfate are soluble because there are no anions that can form an insoluble solid with NH4 + and Na + cations.
