Answer
Sodium Bicarbonate
Explanation
The chemical name of Baking Soda is Sodium Bicarbonate. Its chemical formula is \\( NaHCO_3 \\). It is primarily used in baking as a leavening agent. When it reacts with an acid or is heated, it releases Carbon Dioxide (\\( CO_2 \\)) gas, which causes dough and batter to expand and become fluffy.
Key Points
- > Chemical Formula: \\( NaHCO_3 \\).
- > It is mildly basic, hence used as an antacid to treat heartburn.
- > Used in dry-powder fire extinguishers.
- > Sodium Carbonate (\\( Na_2CO_3 \\)) is Washing Soda.
- > Calcium Carbonate (\\( CaCO_3 \\)) is Limestone/Chalk.
- > Sodium Chloride (\\( NaCl \\)) is Table Salt.
- > Baking powder is a mixture of baking soda and a weak dry acid (like tartaric acid).
