yeah..
HOClO3 is stronger acid than HOCl..
for any acid, its acidic strength depends on the stability of conjugate base..
in HOClO3, when it loses its H+ ion , it makes CLO4 - which has 4 equivalent resonating structures...thus making it more stable...

I nearly fainted when I read this question
mere concepts ki toh dhajji udaa di is question ne
Thank god, everyone answered as per my concepts
my explanation is simple
higher the covalency of central atom, more is its acidity
AND
higher the oxidation state of the central atom, more is its covalency
using these concepts U can clearly see that acidity of HClO4 >HOCll

We could even explain it like this...conjugate base of HClO4 is ClO4- while that of HOCl is ClO- .
Now, greater no. of O atoms means greater dispersal of negative charge by p
-d
back bonding..thus base will be more stable explaining greater acidity of HClO4..















rate if useful.
