Textbook Question

Chapter 4, Problem 108GQ

You have a mixture of oxalic acid, H₂C₂O₄, and another solid that does not react with sodium hydroxide. If 29.58 mL of 0.550 M NaOH is required to titrate the oxalic acid in the 4.554-g sample to the second equivalence point, what is the mass percent of oxalic acid in the mixture? Oxalic acid and NaOH react according to the equation

H₂C₂O₄ (aq) + 2 NaOH(aq) → Na₂C₂O₄(aq) + 2 H₂O(ℓ)sss
