Healthy Foods That Are High in Potassium | Health

Potassium metal reacts very rapidly with water to form a colourless solution of potassium hydroxide (KOH) and hydrogen gas (H2). The resulting solution is basic because of the dissolved hydroxide. The reaction is exothermic. Early in the reaction, the potassium metal becomes so hot that it catches fire and burns with a characteristic pale lilac colour. The reaction is slower than that of rubidium (immediately below potassium in the periodic table), but faster than that of sodium (immediately abo
