Sodium carbonate (Na2CO3), molecular uremu 105.99.Kuchena kwekemikari kunopfuura 99.2% (chikamu chemass), chinonziwo soda ash, asi kupatsanurwa ndekwemunyu, kwete alkali.Iyo inozivikanwawo sesoda kana alkali ash mukutengeserana kwenyika.Iyo yakakosha inorganic kemikari mbishi zvinhu, inonyanya kushandiswa mukugadzirwa kwegirazi rakatsetseka, zvigadzirwa zvegirazi uye ceramic glazes.Inoshandiswawo zvakanyanya mukuwacha, acid neutralization uye kugadzira chikafu.
