Question

What happen when potassium react with cold water?​

Answer 1

It reacts rapidly to form a colorless solution of potassium hydroxide.

Step-by-step explanation:

Potassium metal reacts very rapidly with water to form a colorless basic solution of potassium hydroxide (KOH) and hydrogen gas (H 2). The reaction continues even when the solution becomes basic. The resulting solution is basic because of the dissolved hydroxide. The reaction is exothermic.

Answer 2

the metal melts and floats

Step-by-step explanation:

When potassium is added to water, the metal melts and floats. It moves around very quickly on the surface of the water. The hydrogen ignites instantly. The metal is also set on fire, with sparks and a lilac flame.
