Mg + 2H2O ----> Mg(OH)2 + H2
The magnesium hydroxide is a weak alkali, and provides enough OH- ions to turn the red litmus to blue.

Magnesium reacts very slowly with chilly water, and you may acquire some cm3 of hydrogen a week: Mg + 2H2O -----> Mg(OH)2+ H2 If steam is used, there is relatively a violent reaction: Mg + H2O -------> MgO + H2

Mg + 2 H2O ==> Mg^2+ + H2 (g) + OH^-
so red litmus turns blue
