BeschreibungSodium Phosphate Monobasic Monohydrate is a reagent with very high buffering capacity widely used in molecular biology, biochemistry and chromatography. it can be used as a buffer to adjust pH. In medicine, it is sometimes used as a stimulant laxative before certain operations and medical procedures. Sodium Phosphate Monobasic Monohydrate is often used in foods and in water treatment. It is used as sequestrant, emulsifier, mordant in dyeing, reagent and buffer in foods and analytical chemistry. It is applied as a fireproofing agent and for weighting silk in tanning. It is employed in manufacturing of enamels, ceramics, detergents, boiler compounds, in soldering and brazing instead of borax. Monobasic sodium phosphate is used in baking powders, acid cleansers, electroplating, as a dry acidulant, and in treating boiler water.

synthetischeMonobasic sodium phosphate can be prepared by partial neutralization of phosphoric acid with sodium hydroxide in equimolar amounts: H3PO4+ NaOH →NaH2PO4+ H2O It also can be made by treating disodium hydrogen phosphate with phosphoric acid in proper stoichiometric amount: Na2HPO4+ H3PO4→2NaH2PO4
