Saline hydrides are known to react with water violently producing fire. Can CO2, a well known fire extinguisher, be used in this case? Explain.

Solution :-

Saline hydrides [i.e.,LiH, NaH etc.] react with water to form hydrogen gas

And a base. The chemical equation to represent this reaction is

\( MH_{(g)}+H_{2}O_{(aq)}\rightarrow MOH_{(aq)}+H_{2(g)} \)

This reaction behaves violent and also fire is produced from this.

Dioxygen weights lighter than CO2. CO2 is commonly used as fire extinguisher as it covers the fire like blanket and inhibits the dioxygen supply, thereby dousing the fire.

It can be used in this scenario also. It weights higher than di hydrogen and effective in isolating the burning surface from dioxygen and dihydrogen.
