Reactivity of Metals: Reactions with Water 💥 GCSE Chemistry Learning & Revision

M4A•Episode home

In this episode, we discuss the reactions of metals with water.

Reactive alkali metals like potassium, sodium, and lithium undergo exothermic reactions when introduced to cold water. These reactions yield a metal hydroxide and hydrogen gas.

Potassium exhibits the most energetic reaction, readily igniting the produced hydrogen and the metal itself with a lilac flame.

Sodium reacts vigorously, melting into a mobile sphere on the water's surface.

Lithium demonstrates the mildest reaction, steadily fizzing and diminishing as it floats.

The reactivity of these metals with water follows the order: potassium > sodium > lithium.
