Answer:
Physical Properties Observed
Sodium bicarbonate is a white, crystalline powder that sometimes forms lumps. It is odorless and has a bitter, salty taste. At room temperature, it is a solid. Solubility, or the ability of a substance to dissolve in water, is also a physical property.

NaHCO3 has a white, crystalline appearance.
This compound is insoluble in ethanol and slightly soluble in methanol and acetone.
At a temperature of 20 degrees celsius, the solubility of this compound in water corresponds to 96 grams per litre.
Sodium bicarbonate crystallizes in a monoclinic crystal lattice.
Sodium Bicarbonate Structure (NaHCO3)
Sodium bicarbonate molecules feature one sodium cation and one bicarbonate anion. Here, an ionic bond is formed between the positively charged sodium ion and the negatively charged oxygen (which is singly bonded to the central carbon and not bonded to a hydrogen atom).
