Abubuwan sinadarai:
1. Acid da alkaline
Maganin ruwa na sodium bicarbonate yana da raunin alkaline saboda hydrolysis: HCO3-+ H2O⇌H2CO3 + OH-, 0.8% bayani mai ruwa pH darajar shine 8.3.
2. Amsa da acid
Sodium bicarbonate na iya amsawa da acid, irin su sodium bicarbonate da hydrochloride: nahco3+HCL = NaCl+CO2 ↑+H2O.
3. Raddi ga alkali
Sodium bicarbonate zai iya amsawa tare da alkali.Alal misali, sodium bicarbarbonate da sodium hydroxide dauki: nahco3 + naOh = Na2CO3 + H2O;da halayen calcium hydroxide, idan adadin sodium sodium bicarbonate ya cika, akwai: 2NAHCO3+CA (OH) 2 = CACO3 ↓+NA2CO3+2H2O;
Idan akwai ƙaramin adadin sodium bicarbonate, akwai: Nahco3+CA (OH) 2 = CACO3 ↓+Naoh+H2O.
4. Amsa ga gishiri
A. Sodium bicarbonate na iya ninka hydrolysis tare da aluminum chloride da aluminum chloride, da kuma samar da aluminum hydroxide, sodium gishiri da carbon dioxide.
3AHCO3+AlCl3 = Al (OH) 3 ↓+3ACL+3CO2 ↑;3AHCO3+Al (CLO3) 3 = Al (OH) 3 ↓+3AClo3+3CO2 ↑.
