In the absence of organic matter, silver nitrate is not photosensitive. It is easily reduced to silver metal by glucose, tartaric acid, formaldehyde, hydrazine, and sodium borohydride.

Silver is incompatible with oxalic or tartaric acids, since the silver salts decompose on heating. Silver oxalate explodes at 140°C, and silver tartrate loses carbon dioxide. 

L-dihydroxy-succinic acid (L(dexiro)-tartaric acid, CXIII). This result establishes the position of the double bond between C4 and C5 and demonstrates that C4 carries only one hydrogen atom while C5 has attached to it the enolic hydroxyl group. Treatment of the enol CXI with ethereal diazomethane gives 5-methyl-A4-D-glucosaccharo-3,6-lactone methyl ester (CXIY) which upon further methylation with silver oxide and methyl iodide yields 2,5-dimethyl-A4-D-glucosaccharo-3,6-lactone methyl ester (CXV). When the latter is subjected to ozonolysis there is formed oxalic acid and 3-methyl-L-threuronic acid (CXVI). Oxidation of this aldehydic acid (CXYI) with bromine gives rise to a monomethyl derivative (CXVII) of L-ilireo-dihydroxy-succinic acid. 

The effect of salt is to fix or volatilize, according as it is prepared and used. For the spirit of the salt of tartar, if extracted by itself without any addition, has power to render all metals volatile by dissolution and putrefaction, and to dissolve quick or liquid silver into the true mercury, as my practical directions shew. 

Similar active salts are prepared through tartaric acid, in which case a solution of the chloride is treated with silver tartrate. 

The salts of basic tellurium are colourless and are easily hydrolysed in dilute aqueous solution with formation of the dioxide. The addition of tartaric acid checks the separation of the dioxide on account of the formation of the stable acid tellurium tartrate Te(IIC4H406)4,5 which can be obtained in the crystalline condition, as also can the silver telluryl tartrate Aga(Te0)(C4H406)2, analogous to potassium antimonyl tartrate.6... 

There are only scant reports of the reaction of silver ions with aliphatic or aromatic hydroxy acids and only a few stability constants have been reported.264 In general only weak complexes were formed and typical examples include reactions with ascorbic or tartaric acids.
