which is stronger?dilute sulphuric acid or concentrated sulphuric acid

@ renu 
conc . sulphuric is always stronger beacuse its concentrated means it have higher concentration of h+ ions . 
which means its more acidic , and stronger from the dillute sulphuric acid . 
a concentrated solution is always stronger than its dilluted solution . beacuse in dilluted solution , there is more water which is neutral .

Hi!Renu,

            of course concentrated H₂SO₄ is stronger , because the acid is concentrated state means that there is less water molecule and the P_H is less.

Hope it’s helps you.
