The very active metals react with water. For example, calcium reacts with water to form calcium hydroxide and hydrogen gas. Calcium metal has an oxidation nuer of 0, whereas Ca 2+ in Ca (OH) 2 has an oxidation nuer of +2, so calcium is oxidized. Hydrogen''s oxidation nuer changes from +1 to 0, so it is reduced.

Calcium hydroxide | chemical compound | Britannica

In calcium: Compounds. Calcium hydroxide, also called slaked lime, Ca (OH) 2, is obtained by the action of water on calcium oxide. When mixed with water, a small proportion of it dissolves, forming a solution known as limewater, the rest remaining as a suspension called milk of lime. Calcium hydroxide…. Read More.
