Reactivity of Sodium with Water

What happens when sodium reacts with water?

Does sodium metal react violently with water to produce a colourless solution of sodium hydroxide and hydrogen gas?

Answer:

Yes, when sodium reacts with water, it produces a colourless solution of sodium hydroxide and hydrogen gas.

Sodium metal is highly reactive and reacts vigorously with water. When sodium comes into contact with water, it undergoes a single displacement reaction. Sodium displaces hydrogen from water, leading to the formation of sodium hydroxide (NaOH) and hydrogen gas (H2). This reaction is represented by the equation:

2Na(s) + 2H2O(l) -> 2NaOH(aq) + H2(g)

The resulting solution of sodium hydroxide is colorless and basic in nature. The reaction is exothermic, releasing heat energy in the process.

It is important to handle sodium with care due to its reactivity with water and air. Proper precautions should be taken to ensure safety when working with sodium.
