Question

the part that is cut off asks to fins the charge of the whole molecule after redrawing it.

On a glutamic acid molecule, there are three hydrogens could dissociate in water. Each has a unique pka, they are pkai = 2.10, pKa2 = 4.07, pka3 = 9.47, respectively. This molecule is shown in the following figure. Please redraw the correct molecule in a solution with a pH at 11.5, by adding or removing the hydrogens from the functional groups. And indicate the overall charge of pK1=2.10 pH = pka t log [based HO ОН pky2=4.07 NH2 pk.-9.47
