Re: Back Titration Ideas
Hi Guys,
Its where you cant titrate one substance directly against another, so you react A with B in excess and then titrate residual B against C and calculate the amount of A by working out how much of B was used in the first reaction! Hope that makes sense!

Hi Kimmy, from my understanding, thats just a straight forward titration, not a back titration. Cheers M

Re: Back Titration Ideas
We do "Determining the purity of a sample of calcium carbonate". You put the accurately weighed carbonate in excess HCl then titrate the remaining HCl with NaOH. I can try and scan it for you if you want.
