Dipotassium hydrogen phosphate trihydrate

Dipotassium hydrogen phosphate trihydrate is a water-soluble inorganic salt that provides potassium ions and hydrogen phosphate ions, and is used in the preparation of buffer systems and culture media. Dipotassium hydrogen phosphate trihydrate serves as a buffer or source of electrolytes in cell culture, microbial culture, and biochemical experiments, helping to maintain the pH and ionic strength of the solution. In analytical chemistry, dipotassium hydrogen phosphate trihydrate is used as a reagent for determining calcium and magnesium ions in water samples.
