Reactions of group II elements with water

Beryllium has no reaction with water;

Very clean Magnesium reacts slowly with water to form colorless solution of magnesium hydroxide.

Magnesium burns with bright flame in steam to form white crystal of magnesium oxide and hydrogen gas,

Mg(s) + 2H₂O(l)   → Mg(OH)₂ (s) + H₂ (g)

Mg (s) + H₂O (g)   → MgO(s) + H₂(g)

Calcium, strontium and barium react with water with increasing vigor to give off effervesce of hydrogen (g) and colorless solutions of hydroxides.

Ca(s) + 2H₂O(l) →  Ca(OH)₂(s) + H₂(g)
