Reactions Of Metals With Water

The video explores the reactivity of different metal groups with water. Group 1 alkali metals react vigorously, forming metal hydroxides and hydrogen gas. Lithium reacts gently, while potassium's reaction is more violent. Group 2 alkali earth metals are less reactive; beryllium is inert, magnesium reacts slightly, and strontium forms a solid hydroxide. Transition metals and elements like tin and lead are generally inert in water. Aluminum forms a protective oxide layer, preventing further reaction.

What happens when alkali metals react with cold water?

Describe the reaction of potassium metal with water and its consequences.

How do the reactions of group two metals with water differ from those of group one metals?

Explain the role of lithium hydroxide in industry.
