Acids and Bases Experiment

The document describes an experiment to determine whether various household products are acids or bases. The experiment involves using litmus paper and pH paper to test products like tomato sauce, bleach, dish soap, soda, and vinegar. Results are recorded in tables showing that products like bleach are bases, while vinegar and soda are acids. Students are asked questions about commonalities among acidic and basic household products.

Acids and Bases

Activity #1

I. Introduction:

II. Objectives:
At the end of the experiment, the students should be able to:

a. Determine if a product commonly used at home is an acid or a base.


b. Identify the scale of the acidity or the basicity of some products.

III. Materials:

Red and blue litmus paper Paint


pH paper Cologne
watch glass Tea
Soapy water Salt solution
Tomato sauce Soda
Bleaching agent Fish sauce
Coffee Orange juice
Water Toothpaste
Oil Lotion
Liquid medicine Fresh milk
Vinegar Dishwashing soap
Soy sauce

IV. Procedure:

A. Identify whether the products are acidic or basic.


1. Prepare all the necessary materials.
2. Pour a small amount of liquid sample to the watch glass.
3. Dip the red and blue litmus papers to the sample.
4. Observe the color change of the papers.
5. Write the data on the table 1 below.

B. Identify thepH scale of bleaching agent, dishwashing soap, soda, water, and vinegar.
1. Pour a small amount of liquid sample to the watch glass.
2. Dip the pH paper to the sample.
3. Observe the color change of the pH paper.
4. Compare the color of the pH paper to the pH scale to identify the acidity or basicity
of the liquid.
5. Write the data on the table 2 below.
