Detailed Solution

The above statement is true.
A base that is used as a fire extinguisher is baking soda. Baking soda (NaHCO3) is essentially sodium bicarbonate, which is transformed into sodium carbonate when heated. It also releases CO2 with H2O, which aids in putting out fires. Therefore, baking soda is a base that is used as a fire extinguisher. The reaction is as follows:
                              2NaHCO3Na2CO3+CO2+H2O
