Test Paper for Salt

Materials:

paper, salt, iodine solution

Procedure:

Fill a test tube with water and add a small amount of salt. Stir the mixture until the salt dissolves.

Measure out 3 to 5 mL of iodine solution and add it to the test tube. Stir the mixture again until the iodine has dissolved completely.

What has been done?

When you mix salt with an acid, such as hydrochloric acid or sulfuric acid, you will get an acidic solution that is similar to litmus paper. This means that if you dip paper in this solution, it will turn red when it is wet and turn blue when it is dry.

What has been done?

When you mix an acid with an alkali, such as hydrochloric acid or sodium hydroxide, you will get an acidic solution that is similar to litmus paper.

This means that if you dip paper in this solution, it will turn red when it is wet and turn blue when it is dry. This means that if you dip paper in this solution, it will turn red when it is wet and turn blue when it is dry.
