Question

suggest an activity that can help one to decide whether a given solution is acidic or basic in nature​

Answer 1

Testing with Red Cabbage Juice

This part of the lesson introduces students to the phenomena in a guided manner, using the substances identified by students as acids or bases in the Motivation section. Have students work in cooperative groups to run color tests in small containers with white interiors (like small paper cups). Have them follow the procedure below.

Procedure:

Add one tablespoon (15 ml) of cabbage juice to each of two cups. Describe the color of the juice.

Keep one of the cups as a control (don't add anything to it). To the other cup, add a few drops of liquid acid or base or about one-eighth teaspoon of solid acid or base.

Swirl to mix the test solution and acid or base. Immediately observe the color and describe it. (The solutions will be in the red range with added acid, and in the green to blue range with added base. The colors in base are particularly "fragile" and change from one hue to another in a few minutes.)

Answer 2

Answer:

You can check a solution whether acidic or basic by the following activiti::

Explanation:

Whether a solution is acidic or basic can be measured on the pH scale. When universal indicator is added to a solution, the color change can indicate the approximate pH of the solution. Acids cause universal indicator solution to change from green toward red.
