b) Can you estimate the pH of of solution at the following points of the titration for histadine? (Hint: use those values to guide you during your titration in the lab) Values: 25.00 mL= volume of histadine, .03M=Concentration of Histadine .1254M= Concentration of NaOH Three pkas for histidne are 1.7, 5.97, 9.28 Remember equivalence point is affected by stoichiometry, for example for third equivalence point volume is Ve#3: 3C(His)*V(His)=C(NaOH)*Ve#3 The first equivalence point pH ____________ The second equivalence point _____________ Around the center of the third buffer region _____________

(

b) Can you regard the pH of of key at the aftercited objects of the titration coercion histadine? (Hint: right those values to superintend you during your titration in the lab)

Values: 25.00 mL= dimensions of histadine, .03M=Concentration of Histadine .1254M= Concentration of NaOH Three pkas coercion histidne are 1.7, 5.97, 9.28 Remember equivalence object is unnatural by stoichiometry, coercion copy coercion third equivalence object dimensions is Ve#3: 3C(His)*V(His)=C(NaOH)*Ve#3

The earliest equivalence object pH ____________

The avoid equivalence object _____________

Around the benevolence of the third buffer part _____________
