Kayayyakin sinadarai:
1. Acid da alkaline
Maganin ruwa na sodium bicarbonate ba shi da alkaline sosai saboda hydrolysis: HCO3-+H2O⇌H2CO3+OH-, ƙimar pH na ruwa 0.8% shine 8.3.
2. Yi martani da acid
Sodium bicarbonate na iya yin aiki da acid, kamar sodium bicarbonate da hydrochloride: nahco3+HCL = NaCl+CO2 ↑+H2O.
3. Amsawa ga alkali
Sodium bicarbonate na iya yin aiki da alkali. Misali, sinadarin sodium bicarbonate da sinadarin sodium hydroxide: nahco3+naOh = Na2CO3+H2O; da kuma sinadarin calcium hydroxide, idan adadin sinadarin 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. Martani ga gishiri
A. Sodium bicarbonate zai iya ninka hydrolysis sau biyu tare da aluminum chloride da aluminum chloride, kuma yana 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 ↑.
B. Sodium bicarbonate na iya amsawa da wasu sinadaran gishirin ƙarfe, kamar: 2HCO3-+Mg2+= CO2 ↑+MgCo3 ↓+H2O.
