While clays are not truly soluble in HCl acid, exposure to HCl acid does affect the structure of clay minerals. This paper presents results of acid stability studies conducted with chlorite, illite, and kaolinite clays. ... The leached ions (primarily iron and aluminum) can precipitate as the acid is neutralized.
What does kaolinite react with?
M then kaolinite is stable, - gibbsite is unstable; that is, it will not form or if it has been there, it will react with Si(OH)4 to form kaolinite. ... Protons will react with Al in the clay structure, the clay collapses and Al becomes exchangeable.
Does acid break down clay?
Hydrochloric acid cleans clay minerals by removing free iron oxide from the surface; acetic acid is less effective.
