Determinig the ion concentration in solution

<< < (4/4)

Borek:
It still doesn't make sense to me.

If you know amount of salts added, water hardness masurement doesn't make sense - what you will get is the concentrations of ions put into the solution +/- experimental error. Analysis is just a waste of time.

If you are after equlibrium concentrations, analysis of total concentrations (as in the case of water hardness) will not give you any answer. Equlibrium concentrations can be measured using specroscopic or potentiometric techniques mainly.

arnyk:
^That's true...if all you're after are the ion concentrations then all you need to know is the amount of each salt added and the total volume of solution.

carl_pitt:
i think you can use potentiometry in low ph
