reaction 3: Silver and nitrate and sodium chloride.
Two clear liquids: Silver nitrate solution and sodium chloride solution. A white precipitation forms (a powdery substance that settles to the bottom). was this a chemical reaction or a physical reaction? How do you know?

The reaction between silver nitrate \( \text{AgNO}_3 \) and sodium chloride \( \text{NaCl} \) is a chemical reaction. The formation of a white precipitate, which is silver chloride \( \text{AgCl} \), indicates that a new substance has been created as a result of the chemical reaction.

Here are some reasons why this is classified as a chemical reaction:

1. **Formation of a New Substance**: The white precipitate is a new compound (silver chloride) that forms from the reactants (silver nitrate and sodium chloride). This change in composition indicates a chemical reaction has occurred.

2. **Changes in Properties**: The properties of the reactants (clear solutions) are different from those of the product (a solid precipitate). This alteration in physical state and properties is characteristic of chemical reactions.

3. **Involvement of Ionic Exchange**: In this reaction, there is an exchange of ions between the reactants. The silver ions \( \text{Ag}^+ \) from silver nitrate combine with the chloride ions \( \text{Cl}^- \) from sodium chloride to form silver chloride \( \text{AgCl} \), which is insoluble in water.

In summary, since a new substance is formed along with a change in the physical state, it is a chemical reaction.

**Hypothesis:**

If silver nitrate solution and sodium chloride solution are mixed together, then a white precipitate of silver chloride will form, indicating a chemical reaction has occurred between the two solutions.
