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.
