Question 25 of 30 Submit You prepare a standard NAOH solution for the laboratory, using potassium hydrogen phthalate (KHC§H,0a, abbreviated KHP) as the primary standard. KHP (molar mass = 204.22 g/ mol) has one acidic hydrogen. It took 31.55 mL of the NaOH solution to titrate (react exactly with) 0.750 g KHP. You then use the standard base solution to determine the amount of ascorbic acid in a 500.0 mg tablet of vitamin C. Ascorbic acid (HC6H,O6, molar mass 176.12 g/mol) also has one acidic hydrogen, and is usually mixed with some filler in preparing the tablets. It requires 19.74 mL of the NaOH to titrate (react exactly with) | % 1 4 6. C 7 +/- x 10 0 Tap here or pull up for additional resources LO 00
