n an experiment, a 500.0 mL solution of approximately 0.250 M KOH (56.106 g/mol) solution was prepared. The actual concentration was then determined by standardizing against 1.0050 g of KHP (204.22 g/mol), which required 19.45 mL of the KOH solution. One mole of KOH reacts with one mole of KHP. How would you prepare the KOH solution? After standardization, what will be the exact molarity of the KOH solution? The KOH solution was then used to analyze a sample containing oxalic acid, H2C2O4 (90.03 g/mol). If the titration required 11.33 mL KOH, how many grams of oxalic acid is in the sample? Oxalic acid releases two protons during the reaction.
