Alkali metals react with water. Which two products are formed?

When alkali metals react with water, two products are formed:

1. Hydrogen Gas (H2): This is formed as a result of the reaction between the alkali metal and water. The hydrogen atoms in the water molecule react with the alkali metal to form hydrogen gas.

2. Alkali Metal Hydroxide: This is also formed as a result of the reaction. The remaining OH- ions in the water molecule combine with the alkali metal ions to form the alkali metal hydroxide.

So, the general equation for this reaction is:

Alkali metal (M) + Water (H2O) --> Alkali metal hydroxide (MOH) + Hydrogen gas (H2)

For example, if the alkali metal is Sodium (Na), the reaction would be:

Sodium (Na) + Water (H2O) --> Sodium hydroxide (NaOH) + Hydrogen gas (H2)
