Chemical compound
Silver lactate is an organic chemical compound, a salt of silver and lactic acid [ 1] with the formula CH3 CH(OH)COOAg.[ 2] [ 3]
Silver lactate can be made by the reaction of silver carbonate with lactic acid .
Physical properties [ edit ]
Silver lactate forms light gray crystals.[ 4]
Silver lactate is soluble in water, slightly soluble in ethanol .
Silver lactate forms a crystalline hydrate of composition CH3 CH(OH)COOAg•H2 O.
Silver lactate is a reagent for the precipitation of uric acid .[ 5]
Chemical properties [ edit ]
The compound reacts with triphenylphosphine gold chloride in a mixed solvent of benzene and dichloromethane to obtain colorless triphenylphosphine gold lactate.[ 6]
The compound reacts with a tetraphosphine ligand, dppbpda, to obtain a coordination polymer [(dppbpda)Ag4 (CH3 CH(OH)COO)4 ]n .[ 7]
