### Part G

**Question:**

What solution can you add to a mixture of Ag⁺ (aq) and Zn²⁺ (aq) to precipitate one cation while keeping the other cation in solution?

**Options:**

- ○ NaCl(aq)
- ○ CH₃COONa(aq)
- ○ K₂SiO₃(aq)
- ○ Al(NO₃)₃(aq)

**Buttons:**

- Submit
- Request Answer

### Explanation

In this question, you are asked to choose a solution that will selectively precipitate one of the cations, Ag⁺ or Zn²⁺, from an aqueous mixture, allowing the other cation to remain dissolved. Consider the solubility rules and the formation of precipitates when each of these solutions is added.

Expert Solution
Step 1

In this case, the solution which forms a selective precipitate with one cation and not with the other should be added. 

Since zinc is less reactive than sodium, it cannot replace sodium from its respective salt.
