Activity 2

In this activity, you will distinguish between acidic and basic mixtures based on

the color reactions to an indicator. USE your prepared indicator and the listed

materials.

Procedure:

1. Place 1 teaspoon of each sample in each well of the egg tray or plastic cup.

2. Add ½ teaspoon of the plant indicator to the first sample. If the sample is

solid, wet a pinch of the solid with about ½ teaspoon of distilled water.

3. Note the color produced. Record your observations in the table of observation.

Direction: Complete the table by identifying the nature of sample using the

color scheme given:

Strongly acidic: red to pale red

Weakly acidic: blue

Weakly basic: green

Strongly basic: yellow
