Solution

When a small piece of potassium is added to water, you could observe:

  1. A vigorous reaction: Potassium reacts violently with water, producing hydrogen gas. This reaction is exothermic, meaning it releases heat, and can cause the hydrogen gas to ignite.

  2. Formation of potassium hydroxide: The reaction between potassium and water produces potassium hydroxide, which is a strong alkali that dissolves in water to produce a solution with a high pH. This can be observed as a color change if an indicator is used.
