Question: why are hcl hno3 and h2so4 strong acids?
Answer: Now comparing HCl and h2so4 we will get that HCl completely dissociate in h+and cl- whereas h2so4 dissociate into h+and hso4- .,hso4- itself being acidic in nature do not dissociate again to give h+ ion ,hence HCl is stronger than h2so4. Why is nitric acid stronger than nitrous acid?
