(1) Mokhoa oa asiti

Ka kakaretso, mokhoa oa asiti ke ho arabela ka silicate e qhibilihang le sulfuric acid (kapa li-acid tse ling), ha mokelikeli oa karabelo o fihla boleng bo itseng, emisa karabelo ea asiti, ho tsofala, ebe o sefa le ho hlatsoa ka metsi khafetsa, tlosa Na2S04, romela e omme, e sithabetseng ho fumana sehlahisoa.

(2) Mokhoa oa Sol

Taba ea pele, asiti ea hydrochloric le silicate ea sodium lia arabela ho hlahisa mahloriso a itseng a sol e hlapolotsoeng, tlas'a boemo ba ho futhumatsa le ho hlohlelletsa hanyane, tharollo e hlapolotsoeng ea silicate ea sodium e eketsoa ho sol e lokisitsoeng, 'me tharollo e itseng ea NaC1 ea eketsoa ho arabela ho pH=7~8, 'me boleng ba H bo bolokoa ka taolo ea alkaline, ho boloka mocheso le ho tsofala, ebe e hlatsuoa ho tlosa chlorine, ebe e sefshoa, e omisoa ebe e pakoa.

(3) Mokhoa oa ho fetola khabone

Ka mokhoa ona, khase ea carbon dioxide e fetoloa carbon ka tharollo ea silicate e qhibilihang ho hlahisa Si02 e nang le metsi le sodium carbonate. Kamora hore karabelo e phetheloe, sehlahisoa se sefshoa esale pele, 'me Na2C03 e tlosoa ka tharollo ea metsi a asiti, ebe e sefshoa, e omisoa, e silakanngoa ebe e pakoa.
