What is KHP chemistry?

Potassium Hydrogen Phthalate (KHP) is a classic primary standard substance in that it is readily available in high purity; is relatively inexpensive; is easy to dry; is neither hygroscopic, oxidized by air, nor affected by Carbon Dioxide (thus making it easy to weigh out); does not undergo decomposition during storage; …

What is an application of KHP?

KHP is used in the manufacture of buffers, organic carbon standards, acidimetric standards and other products. Potassium Hydrogen Phthalate also used in the quality control of Potassium Hydroxide and Sodium Hydroxide solutions, and in the standardization of Perchloric Acid in Glacial Acetic Acid.

What does KHP stand for and what is its molecular weight?

A Method for a Titration

Next, using the weigh-by-difference method, measure a sample of potassium hydrogen phthalate, KHP (1) into a clean, dry 125-mL Erlenmeyer flask and dissolve it in 40 mL of water. KHP (MWT = 204.22 g/mol) is a monobasic acid that contains one mole of neutralizable hydrogen per mole of compound.

How do you find %Khp?

The mass percent of KHP is found by dividing the mass of KHP by the mass of the original sample. 1. Using weighing paper, measure between 0.2500-0.5000 grams of KHP on the electronic balance.

What is the concentration of KHP?

i.e. Moles of KHP=0.4536⋅g204.22⋅g⋅mol−1=2.221×10−3mol .

Why is KHP stored in a desiccator?

Function. Heated samples and beakers, or weighing dish, are cooled in a desiccator to prevent the sample or beaker from gathering moisture as it cools. The interior of the desiccator is dry due to the desiccant at the bottom and because it is sealed to keep outside, moist air from getting inside.

Is KHP Monoprotic or Diprotic?

KHP is a monoprotic acid which provides one H+ ion.

Is KHP soluble in water?

Water
Potassium hydrogen phthalate / Soluble in

Water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth’s hydrosphere and the fluids of all known living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients.

Wikipedia

Is KHP a strong acid?

KHP is a weak organic acid, Sodium Hydroxide is a strong base. When combined, an acid-base neutralization reaction takes place generating a conjugate salt and water as reaction products.

What is phthalate free?

Non-phthalates are essentially plasticizers that are free of phthalates. … While low exposures to phthalates are harmless, there has been recent research suggesting the potentially negative impacts a high exposure of phthalates can have on our health. As such, many consumers are switching non-phthalate plasticizers.

Is KHP a chemical formula?

Is KHP toxic?

Ingestion: May cause irritation of the digestive tract. May be harmful if swallowed. Inhalation: May cause respiratory tract irritation. May be harmful if inhaled.

How do you get KHP?

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.
