It also finds use in the production of chloric acid. It is the acyl fluoride of chloric acid. Its robustness contrasts with the instability of chloric acid and bromic acid. Barium chlorate, Ba(ClO), is a white crystalline solid, the barium salt of chloric acid. Calcium chlorate is the calcium salt of chloric acid, with the chemical formula Ca(ClO). Chloric acid is thermodynamically unstable with respect to disproportionation. Chloric acid, HClO, is an oxoacid of chlorine, and the formal precursor of chlorate salts.
