Recall that in a neutralization reaction between an acid and a base, the products will be water and ... In this lab activity, you will neutralize a colorless soft drink using dilute household ammonia. The indicator used to determine when neutralization occurs will be phenolphthalein, often referred to as phth ...

Procedure:

1. Use litmus paper to determine if the dilute ammonia is an acid or base. Record your results in the data table below.
2. Use litmus paper to determine if the soft drink is an acid or base. Record your results in the data table below.
3. Approximately half-fill a test tube with the colorless soft drink and add 2-3 drops of phenolphthalein.
4. Add dilute household ammonia one drop at a time until ONE drop turns the soft drink barely pink. The pink color should remain for about 30 seconds. This is easier to see if you place the test tube in front of a white piece of paper.
5. Test the product with litmus paper to see if it is an acid, base, or neutral and record your results in the data table below.
