1all three completely dissociate !
HCl, HBr, HI have acid strength in order in aqueous solutions as:???
I thought it should be HI>HBr>HCl, but answer is given to be HI=HBr=HCl
Could sumbody pls explain?

1HEY ADITYA they will dissociate into ions completely in aqueous medium..........

The strength of strong acids and bases is dominated by the auto ionization of water.
In aqueous solutions, the strongest acid and base are the hydronium ion, H3O+, and the hydroxide ion OH- respectively.
Acids HCl, HBr, HI, HNO3, HClO3, HClO4, and H2SO4 completely ionize in water, making them as strong as H3O+ due to the leveling effect of water. Furthermore, strong acids, strong bases, and salts completely ionize in their aqueous solutions.
For example, HCl is a stronger acid than H2O, and the reaction takes place as HCl dissolves in water.
HCl + H2O = Cl- + H3O+
A similar equation can be written for another strong acid.
On the other hand, a strong base also react with water to give the stong base species, OH-.
H2O + B- = OH- + HB
For example, O2-, CH3O-, and NH3 are strong bases. The leveling effect also apply to bases.
3The given three acids are strong .They are not like acetic acid.So in a basic medium all the three acids completely dissociate.So their acidic strength is the same in a basic medium.
1sure the acidic strength of any acid is same in strong basic medium
