What is the molarity of hydrogen ions in a 2.7 M solution of the strong acid #HCl#?

1 Answer

Apr 21, 2016

You have a strong monoprotic mineral acid. #[H_3O^+]# #=# #2.7*mol*L^-1#.

Explanation:

#HCl(g) + H_2O rightleftharpoons H_3O^+ + Cl^-#

This equilibrium lies strongly to the right. Thus, the concentration of hydronium ion, #H_3O^+# #=# #2.7*mol*L^-1#.
