(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) If a 1.0L sample of 5% vinegar was diluted with distilled water so that the final volume was 2.4 L what would be the new concentration in mols dm'? (5) What concentration NaOH should be used for your lab if that is what I did with the original vinegar? (choose the best option) (A) 0.0100 M (C) 0.25 (B) 0.100 M (D) 1.00 M (E) 2.00 M (6) Potassium Hydrogen Phthalate (KHP) is used as a primary standard (to...
I need both of these answered assuming for 5 the volume of NAOH is 100 ml and the actual concentration of acetic acid is 20. (5) What concentration NaOH should be used for your lab if that is what I did with the original vinegar? (choose the best option) (A) 0.0100 M (C) 0.25 (B) 0.100 M (D) 1.00 M (E) 2.00 M (6) Potassium Hydrogen Phthalate (KHP) is used as a primary standard (to standardize basic solutions) because it...
Potassium hydrogen phthalate (KHP) is used to standardize sodium hydroxide. If 15.18 mL of NaOH(aq) is required to titrate 0.5614 g KHP to the equivalence point, what is the concentration of the NaOH(aq)? (The molar mass of KHP = 204.2 g/mol) HCH,0, (aq) + OH (aq) SCH,02 (aq) + H,0(1)
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?
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)

Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory to standardize strong base solutions. It has the unwieldy formula of KHC8H4O4. This is often written in shorthand notation as KHP. How many grams of KHP are needed to exactly neutralize 21.6 mL of a 0.479 M potassium hydroxide solution ? What volume of a 0.379 M potassium hydroxide solution is needed to exactly neutralize 2.09 grams of KHP ?
Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory to standardize strong base solutions. It has the unwieldy formula of KHC8H4O4. This is often written in shorthand notation as KHP. What volume of a 0.498 M potassium hydroxide solution is needed to exactly neutralize 3.34 grams of KHP ? ANSWER: ____mL potassium hydroxide
Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory to standardize strong base solutions. It has the unwieldy formula of KHC8H4O4. This is often written in shorthand notation as KHP. If 2.20 grams of KHP are needed to exactly neutralize 31.2 mL of a potassium hydroxide solution, what is the concentration of the base solution ? ANSWER: is in M potassium hydroxide
