Carbon dioxide gas is neither combustible nor helps combustion. It is heavier than air and cuts off the supply of oxygen from air and hence extinguishes the fire. … Hence, sodium bicarbonate is used in fire extinguishers.
Which soda is used in soda acid fire extinguisher?
The correct answer is Sodium hydrogen carbonate. Soda-acid fire extinguishers comprise sodium bicarbonate and sulphuric acid. It consists of a strong iron vessel with a side discharge nozzle. The iron vessel is filled with a sodium bicarbonate solution.
Why is soda acid fire extinguisher so named?
There is a solution of sodium bicarbonate in water in the fire extinguisher and sulphuric acid in a different bottle within it. … It is heavier than air and cuts off the air’s supply of oxygen, thus extinguishing the flames.
What is the principle of soda acid fire extinguisher?
In a soda acid fire extinguisher, when the knob is struck concentrated sulphuric acid present in the fire extinguisher comes in contact with sodium bicarbonate and produces carbon dioxide that puts out the fire.
What does baking soda turn into when heated?
Baking soda, or sodium bicarbonate (NaHCO3), is a chemical that can undergo a decomposition reaction when heated. At temperatures above 176 degrees Fahrenheit (80 degrees Celsius), sodium bicarbonate starts to break down into three compounds, forming sodium carbonate (Na2CO3), water (H2O) and carbon dioxide (CO2).
How does baking powder differ from baking soda?
What Is the Difference Between Baking Soda and Baking Powder? The primary difference between baking soda and baking powder is that baking powder already contains an acid in the chemical mixture, whereas baking soda needs an acidic ingredient to create the rising reaction.
How is baking soda useful in soda acid fire extinguisher Support your answer with a balanced chemical equation?
Answer: Soda acid fire extinguisher acts by cutting off supply of air. The carbon dioxide is liberated by the action of acid on baking soda ,it increases the percentage of carbon dioxide in air (as it is a non supporter of combustion)
What is soda acid used for?
Soda and Acid
A fire extinguisher removes or displaces the surrounding oxygen, smothering the flames. A soda acid fire extinguisher is an emergency fire protection device that can extinguish or control small fires.
What does a soda acid fire extinguisher contains?
Hint: A soda acid fire extinguisher contains an acid and a hydrogen carbonate, which react together to form carbon dioxide gas and this gas is responsible for stopping the fire.
What are the uses of baking soda?
Baking soda, also known as sodium bicarbonate or bicarbonate of soda, is a popular baking ingredient. It gives foods like bread, cakes, muffins, and cookies a light, fluffy texture.
7. Kitchen cleaner

- kitchen tiles.
- clogged drains.
- tarnished silver.
Why is soda acid fire extinguisher not effective when oil catches fire?
(a) Soda-acid fire extinguisher is not successful in controlling fire due to oils because it uses water to cool the combustible substance. But water is heavier than oil and settles down below the oil particles and oil keeps on burning on the top. Hence, fire cannot be controlled.
Is baking soda flammable?
Baking soda is not a flammable substance and is in fact sometimes used to put out fires due to its carbon dioxide producing properties.
Does baking soda burn?
While it’s generally not harmful, baking soda can irritate the skin. Most people don’t know they are sensitive to baking soda until they start applying it directly to their skin. It’s notorious for causing armpit rashes, redness, and burning for some people when used in homemade or natural deodorants.
Why does baking soda and water react?
When baking soda mixes with water, an exothermic reaction takes place. The chemical bonds of each product bind and release energy. This energy then causes the temperature of the water to rise, although insignificantly. For example: you won’t be able to boil a pot of coffee just by mixing baking soda and water.
