Concentration of HCl?
« on: January 13, 2008, 04:34:22 PM »
We did a lab entitled "Determination of a Titration End Point", adding varying amounts of (25 ml of NaOH at 0.10 M) in a buret to 20.00 mL of HCl below. An indicator told us when the titration was complete and when to stop adding NaOH. We need to find the % in error difference between our results of HCl (in moles of HCl) it took to titrate moles of KOH as compared to the theoretical amount (moles) of HCl as accepted.

My question is how do I find the theoretical amount of HCl that should have been obtained in the titration? It says use stoichiometry, but does anyone have the actual steps? thanks.

Start with balanced reaction equation.
