What is the correct acid name for an aqueous solution of HClO3 ?
Solution
Hint : As we know acid is a chemical species that donates hydrogen ions or accepts electrons or protons. In general it starts with hydro and then ends with -ic acid. There are exceptions to this rule. Not all the acid starts with hydro prefix.
Complete Step By Step Answer:
HOCL(=O)3 perchloric acid,
Cl(+VII);pKa≅−15 , its salts are termed as perchlorates
HOCl(=O)2c chloric acid,
Cl(+V);pKa≅−1. its salts are known as chlorates
HOCl=O chlorous acid
Cl(+III);pka=+1.96 its salts are known as chlorites
HOCl hypochlorous acid
Cl(+I);pka=+7.53 its salts are known as hypochlorite
Increase in oxygen substitution increases overall acidity
Hypochlorite salts are the active ingredient of bleach
So as a potent oxidant, see the below reaction
−OCl+2H++2e−→Cl−+H2O
So we also got HCl hydrochloric acid
Cl(−I) its salts are called as chlorides
So the correct acid name is chloric acid.
Note :
Chloric acid is an oxoacid of chlorine, it is a strong salt with pKa=−2.7 and it has oxidising nature. It is pyramidal in shape. it is thermodynamically unstable. It is colourless liquid and it is corrosive in nature
