Sodium bicarbonate is used in the baking industry.

Use of sodium bicarbonate in baking industries:

• In the baking industry, Sodium bicarbonate $\left({\mathrm{NaHCO}}_3\right)$ is used for making cakes, pastries, etc.
• Reason: It releases carbon dioxide during the baking process, causing the bread to rise and giving cookies a fluffy appearance.
• The reaction of vinegar, and yogurt (edible acids) with baking soda, produces carbon dioxide which makes the cakes and bread fluffy
• Reaction -

$$\begin{gathered} 2{\mathrm{NaHCO}}_3\left(\mathrm{s}\right)\stackrel{\mathrm{Heat}}{\to }{\mathrm{CO}}_2\left(\mathrm{g}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)+{\mathrm{Na}}_2{\mathrm{CO}}_3\left(\mathrm{s}\right) \\ \mathrm{sodium}\mathrm{bicarbonate}\mathrm{carbondioxide}\mathrm{water}\mathrm{sodium}\mathrm{carbonate}. \end{gathered}$$

Hence, Sodium bicarbonate is used in the baking industry.
