How to work out solubility product?
« on: October 23, 2011, 12:36:06 PM »
How do I find the Ksp when ive plotted a titration curve and found the emf at equivilance point. This = 0.252V.

 The cell is (-) SCE | KNO3 (sat'd soln) | Ag+ (aq) | Ag+ (+)

 KCl = 0.1 mol dm-3
 AGNO3 = 0.1 mol dm-3

I've looked everywhere for how to do this. Just need someone to point me in the right direction. Cheers,

Ed

It won't hurt knowing what you titrated with what.

Titrated 25cm^3 0.1 mol dm-3 KCl with 0.1 moldm-3 AgNO3.

Added results to word and attached

How are concentrations of Ag+ and Cl- at equivalence point related to Ksp?
