Question

What are the uses of sodium hyrogencarbonate ( NaHCO3) ​

Answer 1

$\huge\star\mathfrak\red{{Answer:-}}$

❇️Sodium Hydrogen Carbonate are used in making baking powder

❇️used in fire extinguisher

❇️Baking soda thus are used in medicines as an antacid

❇️In the manufacture of aerated water

❇️used to make cleanliness of tiles

❇️when hydrogencarbonate reacts with water

NaHCO3+H2O---->NaOH+H2Co3

❇️The hydrogencarbonate is also known as sodium bicarbonate or bicarbonate of soda

❇️The effect of light intensity on photosynthesis can be investigated in water plants so hydrogencarbonate and water be react

Answer 2

Following are some uses of Baking Soda:

• It is used to prepare baking powder, which is a mixture of baking soda, and a mild, edible acid (like tartaric acid, present in tamarind or imli). This neutralises the bitter taste of baking soda and also gives out carbon-dioxide gas along with water.

2NaHCO₃ + H⁺ (from any acid) ------------------> Na₂CO₃ + H₂O + CO₂

• It is used in soda-acid fire extinguishers because when it reacts with acids, carbon-dioxide gas and water are given off, which extinguish fires.

2NaHCO₃ + H₂SO₄ ------------------> Na₂SO₄ + 2H₂O + 2CO₂

• It is also used for faster cooking and, to rise bread or cake while baking.

2NaHCO₃ -----Δ-------> Na₂CO₃ + H₂O + CO₂

Note:- When it is heated, carbon-dioxide gas is given off, which makes the bread or cake to rise.

More to Know:

• Baking soda is the common name for sodium hydrogen carbonate or bicarbonate.
• It is prepared by adding ammonia and carbon-dioxide to brine (sodium chloride solution in water).

NaCl + H₂O + CO₂ + NH₃ ---------> NaHCO₃ + NH₄Cl
