Question

The equivalence point was reached in titrations of three unknown bases at pH 5.53 (base A), 4.11 (base B), and 6.00 (base C). 
(a) Which is the strongest base?
(b) Which is the weakest base?

Hello everyone today. We have the following problem. Three unknown bases were tight treated at the equivalence point. Base A had a page of 3.67. Base B had a ph of 6.91. And basis C had a ph of 4.28 identified the strongest base and the weakest base. So at their respective equivalence points, there are two factors to take note. The higher the ph the stronger the base to the stronger the base. And of course the lower the ph the weaker the base. And this is because low ph s are are indicative of acidic solutions. And so we see here out of all of these bases that base B has the highest ph. So this B has the highest ph and as a result it is going to be the strongest base. So it's going to be the strongest base. Furthermore, we see that base A. Has the smallest ph or the lowest ph and that's going to make Base A the weakest base. And so with that we have solved our problem overall, I do hope this helped. And until next time
