Acid-base question

Question

Which of the followings statements are true for a 1.0 M solution of the strong acid HCl in water?

 

a.[Cl-]>[H3O+]

b.The pH is 1.00

c.[H3O+]=1.0M

d.[HCl]=1.0M

e.[H3O+]=[OH]-

So far I have c and d, but I'm not sure.

Answer 1

C would be correct but not (d) because HCl ionizes completely so concentration of HCl is near zero, not 1.0.
