An aqueous ethylene glycol (HOCH₂CH₂OH, FW = 62.07 g/mol) solution with a mass of 214.3 mg is titrated with 61.9 mL of 0.0867 M Ce in 4 M HCIO. The solution is held at 60 °C for 15 min to oxidize the ethylene glycol to formic acid (HCO,H) and carbon dioxide. The excess Cet is titrated with 10.57 mL of 0.0479 M Fe²+ to a ferroin end point. What is the mass percent of ethylene glycol in the unknown solution?

The calcium (40.078 g/mol) in a 500.0 mL sample of natural water was determined by precipitating the cation as CaC2O4. The precipitate was filtered, washed, and ignited in a crucible with an empty mass of 32.3555 g. The mass of the crucible plus CaO (56.077 g/moI) was 33.1471 g. A. Calculate the concentration of Ca in water in units of grams per 100 mL of the water. B. What is the molarity of Ca in the water sample?
You are preparing standard acid and base solutions for the laboratory, using potassium hydrogen phthalate (KHC₈H₄O₄, abbreviated KHP) as the primary standard. KHP (molar mass = 204.22 g/mol) has one acidic hydrogen. You prepared solutions of both NaOH and HCl. It took 22.65 mL of the NaOH solution to titrate (react exactly with) 1.55 g KHP. It then took 32.35 mL of HCl solution to titrate 25.00 mL of the NaOH solution. What is the molarity of the HCl solution?
Malic acid (C4H6O5) is a dicarboxylic acid that naturally occurs in the production of bignay wine. Maria was tasked to find out the acid content in a 200.0 mL wine sample by titrating it with a standardized solution of KOH. He was able to establish the working concentration of the KOH solution by using 39.12 mL of it to titrate a primary standard of KHP that weighed 3.021 g. The grams and %w/w of Malic acid present in the 200.0 mL wine sample were then determined by titrating a 20.00 mL aliquot using 48.95 mL of the standardized KOH solution. C4H6O5 (aq) + 2KOH (aq) ↔ K2C4H4O5 (aq) + 2H2O (l) Assume the density of the wine sample is 1.000 g/mL MM of KHP = 204.22 g/mol MM of C4H6O5 = 134.0874 g/mol What is the molar concentration of the prepared KOH solution?…

A chemistry student needs to standardize a fresh solution of sodium hydroxide. He carefully weighs out 150. mg of oxalic acid (H₂C₂O4), a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250. mL of distilled water. The student then titrates the oxalic acid solution with his sodium hydroxide solution. When the titration reaches the equivalence point, the student finds he has used 77.1 mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution.
