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

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.Don't miss out on subscribing for more educational content tailored to help you succeed in your exams.
