500 ml ofDilHCl is kept in beaker and 500ml of conc.H2SO4 is kept in second beaker. Both went through pH test, which among the two have lower pH.
Dil HCl
pH does not depend upon the amount of acid taken; it depends upon the strength of hydrogen in the acid i.e. power of hydrogen. As HCl is stronger acid than H2SO4, the pH of dil. HCl will be more than that of conc. H2SO4.
