When a small piece of potassium is added to water, notable observations can be made, including the following:

1. **Vigorous Reaction**: The addition of potassium to water results in a vigorous and exothermic reaction. You'll observe rapid fizzing as the potassium reacts with water, producing hydrogen gas. The reaction may also produce bubbles, and the heat released can cause the hydrogen gas to ignite, resulting in flames.

2. **Formation of Potassium Hydroxide**: As potassium dissolves in water, it forms potassium hydroxide (KOH). This solution is strongly alkaline, which can be observed if pH indicators like litmus paper are used. The litmus paper would turn blue, indicating the basic nature of the solution.

Overall, potassium reacts violently with water, producing hydrogen gas and potassium hydroxide, with notable heat and light effects during the reaction.
