In the standardization of a 0.02M NaOH solution,4.6g oxalic acid was dissolved in enough distilled water to prepare 100mL of solution. A portion of this solution was used to fill a 50mL burette. Subsequently,25mL aliquots of the secondary standard was pipetted into three Erlenmeyer flasks and two drops of phenolphthalein indicator added. What is the concentration of of the oxalic acid?
