## Questions for Reflection

1. **A blue solution of copper(II) sulfate is mixed with a colorless solution of sodium phosphate, and a blue precipitate is formed. Using the solubility rules, predict the formula of the precipitate, and then write a balanced equation describing the reaction.**

2. **A piece of zinc metal (a silver-colored metal) is placed in a blue solution of copper(II) sulfate. After some time has elapsed, the solution is colorless, a red-brown solid has formed, and the zinc metal has dissolved. Write a balanced single-replacement reaction that is consistent with the above observations.**

3. **Explain why there was no solid material remaining after heating the ammonium carbonate in this experiment. (Hint: See the balanced equation for this reaction.)**

**E. Precipitation (Double Replacement) Reactions**

The subscripts on specific ions in the products are not always the same as the subscripts in the reactants. Note the first reaction: Silver ion has a subscript of one in silver nitrate and two in silver carbonate.

1. Silver nitrate + ammonium carbonate → silver carbonate + ammonium nitrate  
   \[ 2\text{AgNO}_3 + (\text{NH}_4)_2\text{CO}_3 \rightarrow \text{Ag}_2\text{CO}_3(s) + 2\text{NH}_4\text{NO}_3 \] (unbalanced)

2. Copper(II) nitrate + ammonium carbonate → copper(II) carbonate + ammonium nitrate

3. Aluminum nitrate + ammonium carbonate → aluminum carbonate + ammonium nitrate

4. Silver nitrate + sodium phosphate → silver phosphate + sodium nitrate

5. Copper(II) nitrate + sodium phosphate → copper(II) phosphate + sodium nitrate

6. Aluminum nitrate + sodium phosphate → aluminum phosphate + sodium nitrate

**F. Neutralization Reactions**

1. Nitric acid + sodium hydroxide → water + sodium nitrate  
   \[ \text{HNO}_3 + \text{NaOH} \rightarrow \text{H}_2\text{O} + \text{NaNO}_3 \]

2. Sulfuric acid + sodium hydroxide → water + sodium sulfate

3. Phosphoric acid + sodium hydroxide → water + sodium phosphate
