for industrial chemistry there is a prac we need to know on calculating equilibrium constants from experimental results. i know there are heaps of pracs one could do to satisfy this dot pt but wen we did it in class i wasnt around could sum1 fill me in as to the procedure cos i know they're gunna ask it.

cheers

Solubility of PbCl
1. get amounts (5,10,15,20,25 ml) PbNO3 (0.1M)
2. get amounts ( " ) NaCl (0.1M)
3. mix amounts so that they all go to same volume
4. there should be a point where sparkles start to form (ie precipiteate just forms
5. using equilibrium expression, the equilibrium constant can be caluculated

other you could do:
eq constant of weak acid
