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 B are mixed? | empirical formula of precipitate |
|---------------------|-------------------|--------------------------------------------------|----------------------------------|
| lead(II) nitrate    | sodium bromide    | ○ yes ○ no                                       | ❑                                |
| copper(II) chloride | potassium sulfide | ○ yes ○ no                                       | ❑                                |
| potassium hydroxide | iron(II) chloride | ○ yes ○ no                                       | ❑                                |

This table organizes a series of experiments where two solutions, labeled as A and B, are mixed. The goal is to determine if a precipitate forms as a result, and if so, to provide the empirical formula of the precipitate.

1. **Solutions**:
   - **Solution A**: Contains either lead(II) nitrate, copper(II) chloride, or potassium hydroxide.
   - **Solution B**: Contains either sodium bromide, potassium sulfide, or iron(II) chloride.

2. **Precipitate Formation**:
   - The table provides options to indicate whether a precipitate forms when solutions A and B are mixed.

3. **Empirical Formula**:
   - A blank space is provided to fill in the empirical formula of the precipitate if it forms.

Each row of the table corresponds to a specific pair of solutions to test for precipitate formation.
