M of NaOH. The pH of the resulting solution will be nearest
[Suggestions: use an I-C-E table to solve this problem. Don't
forget to use the TOTAL volume when calculating H+ (or
OH-) concentration.
2)In the titration of 50.0 mL of 0.100 M benzoic acid (a monoprotic acid) with 50.0 mL of 0.100 M Na0H, the properties of the solution at the equivalence point will correspond exactly to the properties of
3)The fundamental chemical reaction that underlies a strong
acid/strong base titration is the following:
H+ + OH- -> H2O
What is the value of the equilibrium constant for this reaction
(at 25C)?
