When alkali metals come into contact with water, they produce hydrogen gas and a metal hydroxide. Here's the step-by-step process:

1. Alkali metals are highly reactive and can react vigorously with water. This is an exothermic reaction, which means it releases heat.

2. When an alkali metal (let's take sodium, Na, as an example) reacts with water (H2O), it produces a metal hydroxide (in this case, sodium hydroxide, NaOH) and hydrogen gas (H2).

3. The chemical equation for this reaction is: 2Na + 2H2O - 2NaOH + H2.

4. The hydrogen gas produced in this reaction often catches fire, ignited by the heat of the reaction. This is why alkali metals are stored in oil, to keep them away from the moisture in the air.

5. The metal hydroxide produced in this reaction is a strong base, which means it has a high pH and can be corrosive.
