1. 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: HKC8H404 Mass of KHP used for standardization (g) 0.5306 Volume of NaOH required to neutralize...

A solution of NaOH has an unknown concentration. When 1.396 g of potassium hydrogen phthalate (KHP a monoprotic acid frequently used as an analytical standard) is titrated with the sodium hydroxide the end point is 42.54 mL. Use this information to compute the concentration of NaOH in the solution. The molar mass of KHP is 204.22 g mol1. [OH mol L

Potassium hydrogen phthalate, abbreviated KHP, is used to standardize NaOH solutions. A standard KHP solution is made by dissolving 2.12 grams of KHP in 100.00 mL of water. The KHP solution is then titrated with NaOH solution. It takes 23.12 mL of NaOH to reach the endpoint. What is the concentration of the NaOH?

(6) Potassium Hydrogen Phthalate (KHP) is used as a primary standard (to standardize basic solutions) because it is solid and air-stable, making it easy to weigh accurately. It's solubility in water is 80 g/L. Convert this to mols dm. Molar mass of KHP is 204.22 g/mol (7) State the reaction between your acid component in vinegar and sodium hydroxide. What volume of 0.250 NaOH will react exactly with 25.00 cm of the diluted vinegar in problem 4?

4) Potassium hydrogen phthalate (KHP) is the primary standard for evaluating the concentration of potassium hydroxide (KOH) solutions in terms of moles per Liter. In the course of a typical titration, one mole of KHP neutralizes one mole of KOH. 1.000 grams of KHP (molar mass = 204.2 grams per mole) consumed 43.3 mL of a given KOH (potassium hydroxide) solution. What is the molarity of the KOH solution? (5 points)

11. 12. Potassium hydrogen phthalate (KHP, KHC,H,O,) is also a good primary standard. 20 mL of NaOH was titrated with 0.600 M KHC,H,O, solution. The data was graphed and the equivalence point was found when 15.5 mL of the standard 0.600 M KHP solution was added. The reaction equation is: NaOH(aq) + KHC2H4O2(aq) → KNaC3H.O. (aq) +H2O (0) a. What is the molar ratio of NaOH:KHC,H,04? b. What is the molarity of the NaOH solution? 13. Calculate the amount of...
