How does potassium react with water?

Answer 1

It only creates a purple "cloud" as was stated in the previous answer when phenolphthalein is added to the water. The "cloud" is not a cloud. Hydrogen gas is evolved. Phenolphthalein is clear in acidic conditions, and purple in basic conditions. As potassium is added to the water, potassium hydroxide is created (alkaline/basic) therefore creating the purple colour water, and hydrogen gas is evolved. A link accompanying this shows lithium through to Caesium, potassium included, in water and shows the equation of the reaction. Caesium in particular is very entertaining.

Answer 2

It reacts explosively producing a lot of heat, light and sound. The products being KOH, an alkali accompanied with evolution of Hydrogen gas.It's this hydrogen gas burning that is the explosion.

Answer 3

The potassium metal, on contact with the water, takes a hydrogen atom from it and releases it as a gas, which then ignites from the reaction's heat. Then, the potassium combines with the hydroxide ion it had formed and creates potassium hydroxide, which then dissolves into the unreacted water.

Answer 4

Potassium reacts violently with water, producing hydrogen gas and heat. This reaction can cause the potassium to ignite, resulting in a purple flame. The resulting solution is a basic, colorless potassium hydroxide solution.

Answer 5

yes. potassium does react with water to produce potassium hydroxide and hydrogen gas..!!:P

Answer 6

you get a red glow and it produces hydrogen.

Answer 7

Turtles .... we thought it was a joke until it set on fire and a turtle came out .... it was weird

Answer 8

Yes ,and with air it is stored under oil to prevent contact with water or air.,
