If you add 0.5321 g of benzoic acid to a 100 ml volumetric flask and then add enough water to bring the total volume to 100.00 ml, how many ml of 0.2154 M NaOH solution will be required to completely neutralize the benzoic acid (pKa = 4.204)? 1. At the equivalence point, will the solution be somewhat acidic, neutral, or somewhat basic?
2. If you redo the experiment in question 1 using a 50 ml volumetric flask instead of a 100 ml volumetric flask (but the same amount of benzoic acid), how many ml of 0.2154 M NaOH solution will be required to completely neutralize the benzoic acid?
3. If you accidentally overshoot the neutralization point in the experiment described in question 1 and add 0.40 ml too much of the NaOH solution, what will be the final solution pH?
4. Considering your answers to questions 1 and 3 carefully, which of the stock pH indicators (methyl orange, thymol blue, or phenolphthalein) do you want to use for your titrations with the indicator dye?
