Potentiometric titration
« on: June 09, 2012, 04:59:37 PM »
Hi,

I have to calculate a potentiometric titration. Maybe someone can help me, how I can get the correcht answer, because I don't really know how the calculate the task  :-[

If the initial concentration of the base of 0,2M, whats is the approximate value of its dissociation degree. The 5 possible answers are: 0,25; 0,50; 0,10; 0,70; 0,90.

Thanks a lot :)

This statement doesn't make much sense. Would you say "I have to calculate a car"?

Not enough information. Depends on the base dissociation constant.
