1.	The structure of asparticacid is given below . (HOOC-underset(.^(o+)NH_(3))underset(\|)(CH)-CH_(2)COOH) (A)The pK_(a_1),pK_(a_2), andpK_(a_3) of (A), respectively, are: 1.88,3.65, and 9.60. pK_(a_1) corresponds to the ionisation of the COOH group, of(Roverset(overset(o+)(N)H_(3))overset(\|)(C)H-COOH) pK_(a_2) corresponds to the ionsation of (overset(+)(N)H_(3)) (ammonium ion). what is the pH at isoelectric points (pI)?
Answer» `(pK_(a_(1))+pK_(a_(2)))/(2)` `(pK_(a_(1))+pK_(a_(3)))/(2)` `(pK_(a_(2))+pK_(a_(3)))/(2)` `(pK_(a_(1))+pK_(a_(2))+pK_(a_(3)))/(3)` ANSWER :A
