estion 12 of 15 ncorrect Map this question was mittenby pling Lori Jones at University of Guelph The curve for the titration of 10.0 mL of 0.100 M aniline, C6H5NH2, with 0.100 M HCIO4 is given below. O C6H5NH2 and H30 pH O C6H5NH2 and CoH5NH. o C6H5NH3 and H30 O C6H5NH O C6H5NH OH 0 1 3 4 5 e 7 8 9 10 11 12 13 14 O C6H5NH2 and O volume of HCIO4 Added (mL) What is/are the major species in the solution after the addition of 7.0 mL of acid? Incorrect

Answer 1

C6H5NH2 millimoles = 10 x 0.1 = 1

millimoles of HCl = 0.1 x 7 = 0.7

C6H5NH2 + HCl ---------------------> C6H5NH3+

1 0.7 0 --------------------> iniitla

1-0.7 0 0.7

0.3 0 0.7 -------------------> after reaction .

in this mixture only two species are remainied

C6H5NH2 and C6H5NH3+

so answer : second option
