Sodium carbonate akafi sani da soda, soda ash, soda ash, wanke alkali, classified a matsayin gishiri, ba alkali, sinadaran dabara Na2CO3, karkashin al'ada yanayi ga fari foda ko lafiya gishiri.Babban ka'idar ƙara sodium carbonate zuwa ruwan tukunyar tukunyar jirgi don daidaita ƙimar pH shine amfani da sodium carbonate don narkewa cikin ruwa kuma ya zama alkaline, wanda zai iya kawar da carbon dioxide a cikin ruwan abinci na acidic kuma ya warware lalatawar ruwa mai laushi ko gishiri. ruwa akan tukunyar jirgi da bututu.Sodium carbonate ne mai rauni electrolyte, narkar da cikin ruwa don samar da wani buffer bayani na sodium carbonate da sodium bicarbonate, akwai wani electrolytic ma'auni a cikin bayani, tare da amfani da electrolytic hydroxide, da ma'auni zai ci gaba da matsawa zuwa dama, don haka. pH da ke cikin amsawa ba ya canzawa da yawa.
Sodium carbonate primary hydrolysis tsari:
Na2CO3 Sodium carbonate +H2O ruwa = NaHCO3 sodium bicarbonate +NaOH sodium hydroxide
Sodium carbonate secondary hydrolysis tsari:
NaHCO3 sodium bicarbonate +H2O ruwa = H2CO3 carbonic acid +NaOH sodium hydroxide
Sodium carbonate primary hydrolyzed ion equation:
(CO3) 2-carbonic acid + H2O ruwa = HCO3- bicarbonate + OH- hydroxide
Sodium carbonate secondary hydrolyzed ion equation:
HCO3- bicarbonate +H2O ruwa = H2CO3 carbonic acid + OH- hydroxide
