Problem 94AE

You choose to investigate some of the solubility guidelines for two ions not listed in Table the chromate ion (CrO4 2-) and the oxalate ion (C2O42 - ). 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

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