29Cl2O + H2O → 2HOCl
2ClO2 + H2O → HClO2 + HClO3
Cl2O6 + H2O → HClO3 + HClO4
Cl2O7 + H2O → 2HClO4
29ok look at them in the reverse order..
see wen u dehydrate the acids .....acidic oxides and water are formed...
examples
2HClO4 heat→ H2O + Cl2O7
2HClO2 heat→ H2O + Cl2O3
2HClO heat→ H2O + Cl2O
2HNO3 heat→ H2O + N2O5
2HNO2 heat→ H2O + N2O3

Calculate the ON of N or Cl (depending upon the case) in the oxide. (acidic oxides only)
If it comes same as the ON of N in an acid, then when u hydrate it,,, ull get that acid.
If it comes intermediate between any ON of N/Cl in an acid, then those acids will be formed which have the atom at just higher and just lower ON,
4@Asish : Does this method work out for any type of reactions
I mean in many reactions we face the prob of predicting products na??
