You choose to investigate some of the solubility guidelines for two ions not listed in the table below, the chromate ion (CrO₄^{2 -} and the oxalate ion (C₂O₄^2-).

You are given 0.01 M solutions (A, B, C, D) of four water-soluble salts:

Solution	Solute	Color of Solution
A	Na2CrO4	Yellow
B	(NH4)2C2O4	Colorless
C	AgNO3	Colorless
D	CaCl2	Colorless

When these solutions are mixed, the following observations are made:

Experiment Number	Solutions Mixed	Result
1	A+B	No precipitate, yellow solution
2	A+C	Red precipitate forms
3	A+D	Yellow precipitate forms
4	B+C	White precipitate forms
5	B+D	White precipitate forms
6	C+D	White precipitate forms

Write a net ionic equation for the reaction that occurs in each of the experiments. Identify the precipitate formed, if any, in each of the experiments.
