What is the concentration of H+ in a 0.121 M HCl solution?

1 Answer

The concentration of "H"^+H+ will be "0.121 M"0.121 M.

Explanation:

As "HCl"HCl is a strong acid and hence a strong electrolyte, it will dissociate as

"HCl" rarr "H"^+ + "Cl"^-HClH++Cl

So, the concentration of "H"^+H+ will be "0.121 M"0.121 M (the same as "HCl"HCl).
