For acidification of KMnO4 solution, only H2SO4 is suitable whereas the other mineral acids like HCl and HNO3 are not. HCl is not used because some of the KMnO4 will oxidize chloride ions to chlorine gas.

To find the number of moles for another compound in the same equation: number of moles given to you from compound 1 ÷ the front number for compound 1 × the front number for another compound. Therefore, 4 moles of potassium chlorate must be used to produce 6 moles of oxygen gas.

Because the chlorate ion has a charge of -1, this ion contains one more electron than a neutral ClO3 molecule. Thus, the ClO3- ion has a total of 26 valence electrons.

Preparation of 0.5% chlorine solution: For example, to make a 0.5% dilute solution of chlorine from 5% concentrated liquid household bleach = [5.0%/0.5%] -1 = 10-1 = 9 parts of water; hence add one part of concentrated bleach to nine parts of water.

They are stable in aqueous solution or in the form of salts. Halogens generally form four series of oxoacids namely hypohalous acids (+1 oxidation state), halous acids (+3 oxidation state), halic acids (+5 oxidation state) and perhalic acids (+7 oxidation state). Chlorine forms four types of oxoacids.
