Question

Complete the table below by deciding whether a precipitate forms when aqueous solutions A and B are mixed. If a precipitate will form, enter its empirical formula in the last column. solution A solution B Does a precipitate form when A and Bare mixed? empirical formula of precipitate x 6 ? cadmium acetate manganese(II) bromide O yes no potassium sulfide iron(II) nitrate O yes no ammonium bromide potassium acetate O yes no

Answer 1

1. No, because both the product (Cadmium bromide and Magnesium acetate) of the reaction are soluble in aqueous medium.

2. Yes precipitate will form

Empirical formula = FeS

3.No, because both the product (Ammonium acetate and Potassium bromide) of the reaction are soluble in aqueous medium.
