Q
Na
Reaction with Cold Water
A
Fizzing
Na moves on surface of water
pH = 13
Na(s) + H2O(l) -> NaOH(aq) + 1/2H2
8
Q
Mg
Reaction with Cold Water
A
Slow release of bubbles on surface of Mg
pH = 11
Mg(s) + 2H2O(l) -> Mg(OH)2(aq) + H2(g)
9
Q
Mg
Reaction with Steam
A
Mg glows bright white
White solid formed
Flammable gas formed that easily ignites
Mg(s) + H2O(g) -> MgO(s) + H2(g)
