Assignment:
Benzoic acid is an organic acid with a Ka of 6.5x10^-5. It can also be used as a primary standard like KHP. If benzoic acid were used to standardize NaOH, determine if if the equivalence point is acid, basic, or neutral based on the following criteria?:
pKa < 0 is strong acid
1pKa > 10 very weak
If more concentrated NaOH is used during standardization could this change any of these results or is the pKa a constant?
Provide complete and step by step solution for the question and show calculations and use formulas.
