Caption: Potassium metal reacting with water. The reaction produces hydrogen gas and potassium hydroxide. The heat of the reaction ignites the hydrogen gas produced, which burns with a lilac flame. The indicator phenolphthalein has been added to the water, which turns pink due to the presence of the strongly alkaline potassium hydroxide.
