Let's say I take 80 gr of a weak base, dilute it with 50 ml of water and titrate it with a strong acid. I get a titration curve.
Now I take again 80 gr of the same weak base but this time I dilute it with 200 ml of water and titrate it with the strong acid.
What will be the new titration curve compared to the first one?
And here is what confuses me:
On one hand, the diluted base should have lower ph.
But on the other hand, at half equivalence point, Kb=pOH, and since it's the same base, Kb is the same, and thus pOH and pH at half equivalence point should be the same.
I am also not sure about the end point.
Thanks a lot!
