Khoom npe:Sodium Carbonate

Molecular hom:CH2Na2O4

CAS Nr:5968-11-6

Cov khoom siv molecular:

Chemical Properties:

Sodium carbonate yog xim dawb, yuav luag dawb, lossis xim tsis muaj xim tsis muaj ntsev, ua los ntawm cov hmoov crystalline lossis granules.Nws yog hygroscopic thiab odorless nrog alkaline saj.

Daim ntawv thov:

Cov yam ntxwv tseem ceeb tshaj plaws ntawm cov dej qab zib tshauv hauv kev daws yog qhov pH siab buffered.Piv txwv li, hloov cov tshuaj sodium carbonate los ntawm 0.03% mus rau 30% tsuas yog ua rau cov tshuaj pH hloov ntawm 10.5 mus rau 11.7.Vim li no, hauv daim ntawv thov kev ua ntxhia, dej qab zib tshauv yog siv rau kev tswj pH mus rau qhov siab tshaj plaws ntawm 10.5.
