How does KHP react with NaOH?

How does KHP react with NaOH?

A commonly used primary standard for titration with sodium hydroxide solution is the weak acid potassium hydrogen phthalate or KHP (C8H5O4K). In this reaction as well, one mole of KHP completely reacts with one mole of NaOH. The titration of NaOH with KHP involves adding NaOH from the burette to a known volume of KHP.

What is the reaction between KHP and KOH?

The balanced reaction equation between the weak acid potassium hydrogen phthalate or KHP (C8H5O4K) and potassium hydroxide is as follows: KOH + C8H5O4K → C8H4O4K2 + H2O.

What is the chemical equation for KHP?

Potassium hydrogen phthalate/Formula

How do you standardize Koh with KHP?

Titrate the KHP solution by adding KOH from a buret. Record the initial volume reading to the nearest ± 0.01 mL. You may add the first 15 mL quickly, but slow down as you approach the endpoint so that you are eventually adding base one drop at a time to the flask.

How is the equation for Koh and H2O written?

To show that they are dissolved in water we can write (aq) after each. The (aq) shows that they are aqueous – dissolved in water. The equation for KOH (Potassium hydroxide) and H2O sometimes isn’t considered a chemical reaction since it is easy to change the K+ and OH- back to KOH (just let the H2O evaporate).

How to calculate the concentration of a KHP solution?

) The concentration of a standard solution is known very precisely. Since KHP is available in very pure form, you can make a standard solution by weighing a precise amount of KHP and dissolving it in water to make a precise volume of solution. You will calculate the exact concentration of your KHP solution to four significant

What is the reaction of KHP and NaOH?

The reaction between KHP and NaOH is shown by the balanced equation KHC8H4O4 + NaOH = NaKC8H4O4 + H2O. KHP stands for potassium hydrogen phthalate, which has the chemical formula KHC8H4O4. When KHP and NaOH combine, a positive hydrogen ion leaves the KHC8H4O4 and a negative hydrogen atom leaves the NaOH.

Do you have to titrate Koh with KHP?

This is because KOH is not available in very pure form—it absorbs water from the air. To determine the precise concentration of a KOH solution, you must titrate it with another standard solution, such as KHP. You will use the KHP standard solution that you made in Part 1 in a series of titrations with potassium hydroxide (KOH).
