What is kph in chemistry?
Potassium hydrogen phthalate, often called simply KHP, is an acidic salt compound. It forms white powder, colorless crystals, a colorless solution, and an ionic solid that is the monopotassium salt of phthalic acid.

What are the uses of potassium hydrogen phthalate?
Potassium hydrogen phthalate is used as a primary standard for acid- base titrations as well as for calibrating pH meters. It acts as a buffer in pH determination. It finds application as a useful standard for total organic carbon testing.
What is the chemical formula for KHP?
Is potassium hydrogen phthalate an indicator?
When KHP is used as a basimetric standard (e.g., in standardization of Perchloric Acid in Glacial Acetic Acid), Methyl Violet or Crystal Violet indicator is commonly used….Potassium Hydrogen Phthalate.

How would you prepare a standard solution of potassium hydrogen phthalate?
Preparation of KHP Standard Solution: Purity of the Potassium KHP is 99.9%. Therefore to prepare a 1000 mgC/l standard solution, add 2.13g of KHP in a flask and add enough DIW to make it 1 litre solution. Note that the quantities required change with the % purity of the chemical used.
What is the role of potassium phosphate in DCC media?
Potassium phosphate dibasic is typically used as a component for a wide variety of media used in the culture of microorganisms, also as a component in phosphate buffered saline (PBS). In addition to helping maintain pH, it supplies essential phosphate.

Why is KHP used as a thermal standard?
It is also used as a primary standard for calibrating pH meters because, besides the properties just mentioned, its pH in solution is very stable. It also serves as a thermal standard in thermogravimetric analysis. KHP dissociates completely in water, giving the potassium cation (K +) and hydrogen phthalate anion (HP − or Hphthalate −).
Why is KHP used for acid base titrations?
It forms white powder, colorless crystals, a colorless solution, and an ionic solid that is the monopotassium salt of phthalic acid. KHP is slightly acidic, and it is often used as a primary standard for acid-base titrations because it is solid and air-stable, making it easy to weigh accurately.
