Question

When na2cro4(aq) and agno3(aq) are mixed, a red colored precipitate forms which is?

Answer 1

As you can see from the given reactants, this is a double-replacement reaction where the metals and nonmetals of both reactants interchange to form two new products. The reaction is written below:

Na₂CrO₄(aq) + 2 AgNO₃(aq) --> 2 NaNO₃ (aq) + Ag₂CrO₄ (s)

The red colored precipitate is called Silver Chromate, Ag₂CrO₄.
