Given the titration reaction:
HC2H302 + NaOH = NaC2H302 + H20
a) balance the reaction equation; b) if we have 4.00 mL of HC2H302 and titrate with 32.00 mL 0.100 M NaOH to the end point, calculate the MOLARITY of the HC2H302; c) calculate the % m/v of HC2H302 if we know that the formula weight of HC2H302 (acetic acid) is 60.00 grams/ mole.
b) BONUS- When we reach the hallway point in the titration, then [HC2H302] =
[C2H302-]. What is the pH of the solution at this point? pH BONUS 2 How many mL have been added when [HC2H302] = [C2H302-]? mL. Assume that the pKa of the acetic acid is 1.0x10^-5
c) SUPER BONUS- If the solution is titrated to the end point and [C2H302-] = 0.40 M,
then calculated the pOH (and pH) at the end point. The hydrolysis equation is:
C2H302 - + H2O = HC2H302 + OH- and the Kb is equal to 1.0x10-9. (Answer) pH (answer) рОн
d) SUPER DUPER BONUS - define "the universe" and give two examples!
