I've got a diagram of two titrations; one of a weak (HAc) and one of a strong (HCl) acid, both with NaOH dripping down on 'em.

The Y-shoulder shows the pH value while the X-shoulder shows the number of ml added NaOH.

How do I find out the concentration of HCl and HAc from this?

I tried running a google search, but no matter what search terms I enter, all I end up is with a list of colleges and courses which teach forensics. I am in the 11th grade and I need info on the chemistry behind forensics. Which means that I dont need info on computer forensics or forensic photography etc etc...

So please give me a list of sites from where I can get my required information. And I need this ASAP, becuz I dont have much time left till the deadline.

Thank u.
