Hi everyone, I'm sitting unit 3 AQA chemistry on wednesday but I really don't understand how to do titration calculations! can anyone help? is there an easy way to remember it?
Thank you :) x
Right, I will try and explain them but I don't know if it will help.
The main thing you need for these is the triangle : no. of moles
concentration | volume
1. Use the triangle to find the no. of moles of the alkali
2. use the equation to find the ratio of acid:alkali. This will tell you how many moles of alcohol there are e.g. if the ratio is 1:1 they will have the same number of moles.
3. Use the triangle to find the equation of the acid and you're all done :-)
Remember if the volume is in cm3 then you need to divide it by 1000 to put it into dm3
Hope that helps ***
oh that really does! thank you!:) ***
What exam is it you are doing? **
AQA C3 on Wednesday, how about you?**
I'm doing this exam Wednesday! The CGP book really helps. http://getrevising.co.uk/resources/aqa_chemistry_unit_c3_higher_tier_revision_notes
That is amazing if you don't have CGP :)
yeah I know,
I've already got them!:p good luck :)
oh haha well it explains titrations well. you too! :)
Learn the formula triangle for g/dm3 as well as the formula triangle for mol/dm3!
Is that A-Level?
I am doing OCR salters unit 2 on friday which is AS :-) x
yeah it's not in any of the practice papers I've done so ya know! ooh a-level! good luck :) x x
