Answer: A 15.0-mL sample of an oxalic acid solution
Chapter 4, Problem 4.1c(choose chapter or problem)
A 15.0-mL sample of an oxalic acid solution requires 25.2 mL of 0.149 M NaOH for neutralization. Calculate the volume of a 0.122 M KMnO4 solution needed to react with a second 15.0-mL sample of the oxalic acid solution. (Hint: Oxalic acid is a diprotic acid. See 4.99 for redox equation.)
