Why does potassium react more violently with water than lithium?

WebJun 5, 2024 · The reactions are ongoing this way: Relatively free electrons of potassium reduce water: (1) 2 e X − + 2 H X 2 O H X 2 + 2 O H X −. That leaves metal positively charged. Liquid ammonia, if exposed to alkali metal, reacts with electrons much slower than water, … WebThe sodium reacts and floats on the surface; gas is released and forces the water level down. More sodium can be added. The sodium forms a ball, a sign that it has melted (exothermic reaction). After all the sodium has reacted the gas can be tested by igniting it, using a long match or splint.
