A theoretical question: If you had to perform the ascorbic acid/sodium hydroxide titration without a pH meter, what indicator could be used to detect an endpoint as close as possible to the equivalence point? If you did not have a pH meter reading equipment, how else would you detect equivalence point while performing this titration?
A 15.00 mL mono-protic acid (X) was titrated with 0.20 M NaOH while measuring the pH. A plot of pH verses volume of NaOH gives the following curve. Based on this curve, answer the following. On the titration curve, what is the composition of the solution before the steep rise of the pH? That is before equivalence point. Question 22 options: Base and salt of the base. Base only Acid and salt of the acid Acid only
