Pre-laboratory Questions
A student wants to calculate the concentration (molarity) of a 10.0 mL vinegar sample. The student uses 40.5 mL of 0.25 M NaOH. What is the concentration (molarity) of the vinegar? Credit will only be given if you show your work. The chemical equation is: CH3COOH + NaOH -> NaCH3COO + H2O.
Titration of a 12.0 mL solution of HCl requires 22.4 mL of 0.12 M NaOH. What is the molarity of the HCl solution?
