Titration Diagram
In the Titration diagram, what do the points labeled A,B,C,D, and E stand for? Are they as important as the stoichiometric point?

Re: Titration Diagram
I believe they just highlight data points, so that when you draw the curve with all of your plotted data you would better be able to identify the stoichiometric point. I think those points you are asking about specifically are just the pH of solution as they correspond to the volume of the solution.

Re: Titration Diagram
I think you're good to go as long as you can identify which point the stoichiometric/equivalence point lies in (when y axis is pH7). I don't think the rest of the points mean anything, but you should be able to relate those points to acidity of the titration solution by looking at the pH indicated in the y axis.

Re: Titration Diagram
To be clear, we don't really have to know tritration for the final do we? Is what we have to know basically the stoichiometric point where moles acids added = moles of base sample?

Re: Titration Diagram
I believe that we don't need to know about all the different points on a titration diagram. The main thing is that you should be able to predict whether the stoichiometric point of a titration would be greater than, less than, or equal to 7 based on the acids and bases that interacted. For reference:
Strong Acid + Strong Base = Stoich Point is equal to 7
Strong Acid + Weak Base = Stoich Point is less than 7
Weak Acid + Strong Base = Stoich Point is greater than 7
Weak Acid + Weak Base = don't worry about it yet, that's for 14b!
Strong Acid + Strong Base = Stoich Point is equal to 7
Strong Acid + Weak Base = Stoich Point is less than 7
Weak Acid + Strong Base = Stoich Point is greater than 7
Weak Acid + Weak Base = don't worry about it yet, that's for 14b!
