Answer to the question in the question we have to find there is a table given in the question and from the data given in that table we have to find weight of the acid more precisely molecular weight and the value of the pk a 1 and the pk a 2 so if it is said we have to find the pk 1 pk2 it means that the acid is diprotic so what we have to do we have to plot a graph and to find, we need to plot a graph to find the equivalence point.

Equivalence point and after finding the equivalence point in the strongly acidic solution, the equilibrium will shift to favour h2a.
01:31
Positive as the predominant form of the amino acid in a strongly basic solution a negative will be major species so we had right the conditions what will happen see we had specifically right in the strongly acidic solution h2a positive will be the favorable or predominant form we have right h2a because the acid is diprotic and in the basic medium major proportion will be from the a negative.
02:30
So now we have to plot a curve or we can say a graph kind of thing.
02:37
And on that graph we will find the equivalence point.
02:42
And after getting the equivalence point, we get the ph at which the equivalence point is occurring.
02:49
And after that, at that ph, at one equivalence point, we will get p .k .1.
02:59
At the other equivalence point we will get the pka 2.
03:03
So there is a table given in the question.
03:08
So experimental table.
03:11
So from that we can plot this kind of graph.
03:15
And at this point of graph, we will be plotting our points at which we will be getting our pca values.
03:24
So it will start somewhere between this and it will go like this.
03:29
And here we will be getting the two equivalence point...
