Homework Help: Chemistry

Posted by Paul on Monday, April 2, 2007 at 2:43pm.

0.50 M HI with 0.10 M KOH
pH at equivalence point?

I had another problem like this and I tried to do it the same way b/c I thought that was the right thing to do but it seems as if its not? Can you help?

HI + KOH ==> KI + H2O.

At the equivalence point we will have KI (the salt of a strong acid/strong base) and water. The pH will be 7.0 UNLESS this a complicated problem in which activities are to be used instead of molarity AND we use the Debeye-Huckel theory to calculate ionic strength.
