Correct:
D
Explanation
Cooking soda, also known as baking soda, is chemically known as Sodium Bicarbonate and has the chemical formula NaHCO3. It is a salt composed of a sodium cation (Na+) and a bicarbonate anion (HCO3-). It is widely used in cooking as a leavening agent because it reacts with acidic components in batters, releasing carbon dioxide (CO2), which causes the expansion of the batter and forms the characteristic texture in cakes and breads.
Other options explained:
- NaCl: Sodium Chloride, commonly known as table salt.
- NaOCl: Sodium Hypochlorite, used as a bleaching agent and disinfectant.
- Na2CO3: Sodium Carbonate, commonly known as washing soda or soda ash.
