PRELAB QUESTIONS: Please do not give short (one or two word answers) to the questions. ALL Answers must be written by hand directly into your lab notebooks. 1. Complete and balance the following neutralization reaction, and identify the acid, the base, the conjugate acid and the conjugate base. Also identify which acids are strong and which are week a. CH3CO2H + NH3 b. + NaOH c. HCl + NH3 d. H2SO4 + NaOH 2. A 25.00 mL sample of an unknown monoprotic weak acid is titrated to the equivalence with 14.65 mL of 0.09861 M NaOH. Calculate the concentration of the unknown weak acid. 3. Why are we indicators for this experiment and not a pH meter? 4. What is the problem if you over titrate your reagents in this experiment?
