A 0.9600 M NaOH solution was diluted with a factor of 4. Then the diluted solution of NaOH was titrated against an unknown acid. The volumes of NaOH(aq) titrated are shown in the table below. Volumes of NaOH(aq): Rough titration First Second Third Third titration titration titration titration Final burette reading: 19.00 34.05 20.86 36.01 23.57 (mL) Initial burette reading: (mL) 19.00 19.07 5.76 21.02 8.54 14 -98 is.ld 14.99 15.0g The molarity of the unknown acid is 0.08108 M and the volume of the unknown acid used in each titration is 14.80 mL. (1) Was the unknown acid monoprotic, diprotic or triprotic? Show your calculations and reasoning.
