titration types

Postby samanthalee14adis1G » Fri Dec 02, 2016 5:58 pm

Is there such a thing as a weak acid weak base titration type? If no, why not?

You could technically do a titration for a weak acid and a weak base; however, this would be very difficult as both acids and bases would change the overall pH of the solution. You would not be able to differentiate between the two. In a tritration, you are able to choose the titrant to add to the unknown sample. Since it is unknown whether the sample is a strong or weak acid/base, you would choose a strong titrant base/acid respectively to add to the sample.

Therefore, there are four titration types: strong acid titrant/strong base sample, strong acid titrant/weak base sample, strong base titrant/strong acid sample, and strong base titrant/weak acid sample.

Hope this helps! :)
