Inorganic chemistry term for the acid of antimony in the +3 oxidation state. Used in specialized contexts such as analytical chemistry and materials science.
亜アンチモン酸は、アンチモンの酸化物を水に溶かすと得られる。
Antimonious acid is obtained by dissolving an oxide of antimony in water.
Refers to antimonic acid (Sb in +5 oxidation state), while 亜アンチモン酸 is the +3 state acid.
