In the standardization of NaOH, 38.76 mL of NaOH was required for 0.8169 g potassium acid phthalate. Estimate the accuracy we should expect in the molarity of the NaOH solution assuming the weighing error is ±0.1 mg, a buret reading error is ±0.02 mLbalance, and an additional uncertainty of ±0.03 mL using the indicator for the end-point determination.
