A solution of sodium hydroxide (NaOH) was standardized against potassium hydrogen phthalate (KHP). A known mass of KHP was titrated with the NaOH solution until a light pink color appeared using phenolpthalein indicator. Using the volume of NaOH required to neutralize KHP and the number of moles of KHP titrated, the concentration of the NaOH solution was calculated.
Molecular formula of Potassium hydrogen phthalate: HKC8H4O4
Mass of KHP used for standardization (g) 0.5103
Volume of NaOH required to neutralize KHP (mL) 13.06
Calculate the concentration of NaOH solution in (mol/L)
Calculate the weight/volume percentage of the vinegar solution (g/100 ml).
Calculate the amount of ascorbic acid in the Vitamin C tablet in (mg).
Please show the work and all teps to the answers, Thank You!
