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)
