Dear student

Since HCl is a strong acid it undergoes complete dissociation

HCl -----> H+ + Cl-

Since HCl is a monobasic acid, only one mole of hydrogen in
liberated when it dissociates
Therefore [H+]= 10-4 M

C o n c e n t r a t i o n o f H + i o n s i n 10 - 4 M H C l s o l u t i o n i s : ( 1 ) 10 - 4 ( 2 ) 10 - 10 ( 3 ) 10 - 14 ( 4 ) N o n e o f t h e s e

$C o n c e n t r a t i o n o f H^{+} i o n s i n 10^{- 4} M H C l s o l u t i o n i s : (1) 10^{- 4} (2) 10^{- 10} (3) 10^{- 14} (4) N o n e o f t h e s e$
