WitrynaA student titrates 0.2717 grams of KHP (KC 7 H 4 O 2 (COOH), MM = 204.222 g/mol) with 10.65 mL of NaOH to reach the endpoint. What is the concentration of the NaOH? KC 7 H 4 O 2 (COOH) (aq) + NaOH (aq) → H 2 O (l) + NaKC 7 H 4 O 2 (COO) (aq) Expert Solution Want to see the full answer? Check out a sample Q&A here See … WitrynaTitration of NaOH solution: 8. Record the initial volume of NaOH solution to 0.1 ml (it does not have to be 0.0ml). 9. Using a spatula, transfer 0.10 g (within ± 0.01 g range) of potassium hydrogen phthalate (KHP) onto a folded weighing paper, tared on the balance. Record the actual mass of KHP. WitrynaThe volume of NaOH used in the titration is: (40.55 mL - 10.45 mL) = 30.10 mL. After standardizing the sodium hydroxide solution, we will then determine the KHP … shell oil pay online
