Titrations

Hi all, I know how to talk about a titration experiment but how do you do the calculations for it ? I would really appreciate It if you could give me an example as well top notch xD but really like help

1. Write down reaction equation
2. Work out stochiometric ratio (ratio of products that react, e.g. 1 mole H3PO4 --> 3 moles NaOH). This can easily be done by comparing the number hydrogen and hydroxide ions.
3. Work out number of moles of Solution A (n = c * v)
4. Use this to work out number of moles of solution B
5. Work out concentration using c = n/v

Example - 20cm^3 of 0.1mol/dm^3 NaOH reacts with 25cm^3 HCl. What is the concentration of the HCl?

Hope this helps!

Wow! thanks I feel kinda dumb asking that, but what was the n=c*v stand for and c=n/v I think I know but could you help even more

n = number of molesC = concentrationV = volumeYou can easily check using dimensional analysis on your units for concentration (mol/dm^3 implies it is number of moles divided by dm^3, which is the unit of volume )Posted from TSR Mobile

Thanks, sort of understand it to be honest I don't know how I got an A* in c3, but what do you mean about the hydroxide ions allowing you to work out the moles or something on your first post
