Ngwongwo kemịkal:
1. Acid na alkaline
Ọkpụkpụ osisi nke sodium bicarbonate adịghị ike ike alkaline n'ihi hydrolysis: HOC3- + H2O⇌H2CO3 + OH- 0.3.
2. Meghachi omume na acid
Sodium bicarbonate nwere ike meghachi omume na acid, dị ka sodium bicarbonate na hydrochloride: Nahco3 + H2O.
3. Mmeghachi omume na alkali
Sodium bicarbonate nwere ike meghachi omume na alkali. Iji maa atụ, sodium bicarbarbonate na sodium hydroxide mmeghachi omume: Nahco3 + Naoh = Na2 + H2O; na calrium hydroxide mmeghachi omume, ma ọ bụrụ na ego ole sodium sodium sodium jupụtara na, enwere: 2nahco3 + ca (oh) 2 = na2co3 + 2h2o;
Ọ bụrụ na enwere obere ọnụọgụ sodium, enwere: Nahco3 + ca (oh) 2 = cpo3 ↓ + na- nah + Nafia.
4. Mmeghachi omume na nnu
A. sodium bicarbonate nwere ike okpukpu abụọ nke aluminom chloride na aluminom chloride, ma mepụta aldroxide aldroxide, sodium nnu na carbon dioxide.
3ahco3 + Alcl3 = Al (Oh) 3 ↓ + 3acl + 3CO2 ↑; 3ahco3 + Al (Clo3) 3 = Al (Oh) 3 ↓ + 3aclo3 + 3co2 ↑.
B. sodium bicarbonate nwere ike imeghachi omume ụfọdụ ngwọta nnu, dị ka: 2hco3- + MG2 + ↑ + MGCO3 ↓ 'H2O.
5. Mkpebi site na ikpo ọkụ
