Can someone explain to me the concept of what is occurring during a weak acid and strong base titration between unknown CH3COOH and NaOH in full detail am writing a lab report. It would be helpful to explain the purpose behind each of the calculations used to find the concentration of CH3COOH. The endpoint was reached at 24.3 ml by the way. Tools Burette: 24.3 mL 1.00 M NaOH Flask: 100 mL of CHCOOH (Unknown concentration) Indicator: Phenolphthalein Reset ..JI K DESCRIPTION WORKSHEET Burette: 1.00 M NaOH Flask: 1.00 M NaOH is a strong base. Mystery CH3COOH Mystery CHCOOH is a weak acid. The initial pH of the solution is 2.7. Indicator: Phenolphthalein Phenolphthalein is colorless when pH is below 8.2 and pink when pH is above 8.2. Balanced chemical equation: CHCOOH + NaOH CH3COONa+ HO pH at equivalence point: 9.0
