what am I doing wrong?

Analytical chemistry G mquiry Actiitv Predicting Acid/Base Titration Part 2: Predicting equivalence varying react point volum es for titrations with Stoichiometries. Complete each of the three tables. on i Titration of 50 mL0.163 M Ha with 0.253 M NaoH. a Titrand species: HCI blTitrant species uation to describe reaction of ttrand and titrant species dl To n to describe reaction of titrand and titrant species e) Netianik n to describe reaction of titrand and titrant species Titrand millimoles TO ID3M TI) Titrant milli. Mob equivalence g) Titrand milli milli. h) Titrant volume addei at equivalence pt. (mL Total volume at equivalence 32. 72.21 mL [Na' (or at equivalence, Oga M k) pH at equivalence Regarding part k): Any time you calculate or predict a pH value you first need to know a concentration of hydrogen ions in solution. At the equivalence point all the H ions that were in the titrand solution have been consumed by added 0H ions. Where do the hydrogen ions come from at the equivalence point?

Explanation / Answer

answer= [k]   at equivalent point solution be NEUTRAL pH =7.0 ..its neutralizing reaction.

ABCDE ARE CORRECT THAN PROCEED WITH F =8.15 milimole [50x0.163] THAN G both have 1;1 ratio ions,also both have same normality and molarity.[H] as given by you 32.21 ml [I] toal is 50+32.21 =82.21 ml [J]

8.15/82.21=0.099 M  [ L] and [m] both have same equivalent 8.15 miliequivalent...because normality same as molarity...
