In Year 1 chemistry, we can watch how neutralization reactions happen using a few simple ways. Here are three methods you can try:

1. pH Measurement:

   • You can use pH indicators like litmus paper or phenolphthalein.
   • Look for changes in pH. Neutralization usually happens at a pH of 7.

2. Titration:

   • You can do a titration by carefully adding an acid to a base, or the other way around.
   • You can find the neutralization point using this formula:
     ( \text{M}_1 \cdot \text{V}_1 = \text{M}_2 \cdot \text{V}_2 )
     Here, ( M ) stands for molarity (which means how concentrated a solution is) and ( V ) is the volume.

3. Temperature Change:

   • Measure the temperature before and after the reaction. Neutralizations usually release heat, making the temperature go up.

These methods help us see how acids and bases behave when they mix together.
