Answer 2

$\star$The similarity in the action of baking soda and soda acid fire extinguisher is as follows:

• Baking soda on reaction with an acid produces salt of acid , water and carbon dioxide.

• The carbon dioxide (as a product) is a non-supporter of inflammation and hence acts as an extinguisher.

• The fire extinguisher cylinder contains dilute sulphuric acid in a bottle. When the bottle is inverted in fire , the sodium bicarbonate reacts with sulphuric acid to produce carbon dioxide.

• Hence fire is extinguished.

$\boxed{\sf{H_{2}SO_{4}+NaHCO_{3}\rightarrow H_{2}O+CO_{2}+Na_{2}SO_{4}}}$

Hope It Helps.
