Alias: Potassium hydrogen carbonate
Molecular Formula: CHKO3
Molecular Weight: 100.12 g/mol
IUPAC Name: Potassium hydrogen carbonate
Structural Information
- Structure Type: Inorganic bicarbonate salt, ionic compound
- Structural Features: Composed of potassium cations and bicarbonate anions, weak acid salt with moderate chemical activity.
Physical & Chemical Properties
- Appearance: White crystalline powder or colorless transparent crystals
- Odor: Odorless
- Melting Point: Decomposes at about 100 °C
