What is the chemical name of baking soda?

Sodium hydrogen carbonate

The correct answer is option 2. Sodium hydrogen carbonate.

Baking soda, also known by its chemical name sodium hydrogen carbonate or sodium bicarbonate, has the molecular formula NaHCO₃.

Baking soda is a white crystalline powder that consists of sodium ions (Na⁺), hydrogen ions (H⁺), carbonate ions (CO₃²⁻), and water (H₂O). Its chemical formula, NaHCO₃, indicates the presence of one sodium (Na) atom, one hydrogen (H) atom, one carbon (C) atom, and three oxygen (O) atoms.

In summary, baking soda, or sodium hydrogen carbonate, is a versatile compound with multiple applications, particularly in cooking, cleaning, and neutralizing acidic substances. Its ability to release carbon dioxide gas makes it valuable in various culinary and household scenarios.
