We are determining the molarity of HCl by titration of HCl. What would be the complete equation and the net ionic equation? THanks

What are you titrating it with? Won't that make a difference in the equation we write?

It's titration of HCl with NaOH.

molecular equation:
HCl + NaOH ==> NaCl + H2O

net ionic equation:
H^+ + OH^- ==> H2O

You must learn to do these by yourself. Please post anything you don't understand about the above.
