The pH is acidic because within the extract there are other compounds as well. I'll try to understand the experiment a little better and try to figure it out. Thanks for all your help.
Sorry I do mean the end point of citric acid when it is titrated with strong base. Thanks.
The analyte is an extract of a vegetable. It contains alkaloids which I hope the citric acid would interact with. Initally when we tested the pH of the vegetable extract we were quite surprised that...
1.Thanks a lot for your response . I've been trying to read as much as I can on the subject of polyprotic acids, but I am still confused.
2.Information on the polyprotic acid I will be using
The acid I am using now is citric acid ( H3C6H5O7) which has pKa values of 3.13, 4.76, and 5.41 . The...
Homework Statement
I'm currently doing an experiment that requires me to use a weak polyprotic acid (triprotic) to neutralize a strong base. I'll be using the acid as the titrant. I need to find out the molarity of the base. Can I still use the M1V1=M2V2 equation in this case?
2. The...
