a. How would you prepare the KOH solution? b. After standardization, what will be the exact molarity of the KOH solution? c. 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.

Question
In an experiment, a 500.0 mL solution of approximately 0.250 M KOH (56.106 g/mol) solution wasprepared. 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 ofKHP. a.
