Sodium carbonate , tseem hu ua ntxhua dej qab zib, yog ib qho khoom muaj nyob hauv cov ntxhua khaub ncaws. Thaum yaj hauv dej , nws nyiam tsim cov kev daws teeb meem nrog pH cov nqi ntawm 11 thiab 12.

Ntxiv rau qhov no, pH ntawm sodium carbonate yog dab tsi?

pH ntawm Common Acids thiab Bases

Puag Lub npe 1 mM
NaAcetate sodium acetate (CH3COONa) 7.87
KHCO 3 potassium hydrogen carbonate 8.27
NaHCO 3 sodium hydrogen carbonate 8.27
Be(OH) 2 beryllium hydroxide 7.90

Qhov thib ob, yog sodium carbonate yog cov kua qaub lossis lub hauv paus? Sodium carbonate yog ntsev tsim thaum sodium hydroxide (muaj zog puag ) reacts nrog ib qho twg kua qaub muaj carbonate ion (CO3 kua qaub muaj cov carbonate ion yuav ib txwm tsis muaj zog kua qaub.

Ib yam li ntawd, tib neeg nug, puas yog sodium carbonate nce pH ntawm dej?

Cov txheej txheem kev lag luam ib txwm tau siv sodium bicarbonate (baking soda) rau tsa totalalkalinity thiab sodium carbonate (soda ash) rau nce PH - qhov kev zam yog tias ob qho tag nrho alkalinity thiab pH yog qis . Sodium carbonate yuav ua rau muaj kev cuam tshuam rau ob leeg pH thiab totalalkalinity.

sodium carbonate ua dab tsi hauv dej?

Thaum yaj hauv dej , sodium carbonate tsim carbonic acid thiab sodium hydroxide. Raws li lub hauv paus muaj zog, sodium hydroxide neutralizes gastric acid yog li ua asan antacid. Sodium carbonate yog ib organic sodium ntsev thiab a carbonate ntsev.
