NH3 is neutral and KOH is acidic. c. Both are neutral. d. NH3 is acidic and KOH is neutral. ac. NH3 is neutral and KOH is basic. 14) On the same graph, sketch the titration curves for both scenarios listed above. Provide the sketch in the blank space below. Your titration curve for NH3 will be a normal line while your titration curve for KOH will be a dotted line.

When titrating a 25 mL solution of 0.20M CH3COOH with 0.10M KOH, you realize you forgot to add an indicator initially. You've added 10 mL of KOH to the flask of acid. Ka of CH3COOH = 1.8 x 10^-5 1) Calculate the pH at this point 2) What color would your solution be if you add 40 mL KOH more. And a few drops of clorophenol blue indicator at this point. Why?
