Potassium dihydrogen phosphate

Detailed introduction

1. Product Description

Potassium dihydrogen phosphate is colorless tetragonal crystal or white crystalline powder, with a relative average molecular mass of 136.09, stable in air and soluble in water. At 90 ℃, the solubility is 83.5g/100ml of water, the aqueous solution is acidic, and the pH value of 1% potassium dihydrogen phosphate solution is 4.6. Insoluble in alcohol. There is deliquescence. When heated to 400 ° C, it melts into a transparent liquid, which solidifies into an opaque glassy potassium metaphosphate after cooling. For the preparation of buffer, determination of arsenic, antimony, phosphorus, aluminum and iron, preparation of phosphorus standard solution, preparation of culture medium, determination of serum inorganic phosphorus, alkaline phosphatase activity.

3. Product Application

pH regulatorDihydrogen phosphate ions and monohydrogen phosphate ions are one of the most important buffer systems in the human body, which play an important role in maintaining the stability of pH value and acid-base balance in the body. The phosphate buffer system is one of the most widely used buffer systems in biochemical research and has the following advantages:

1) easy to prepare into various concentrations of buffer;

2) The applicable pH range is wide;

3)pH is little affected by temperature;

4) After buffer dilutionThe change of pH is small, such as the change of pH after ten times dilution is less than 0.1.

Preparation of phosphorus standard solutionDetermination of arsenic, antimony, phosphorus, aluminum and iron, preparation of phosphorus standard solution.

Preparation of mediumPreparation of various media for haploid breeding, preparation of bacterial serum test of leptospirosis medium.
