CAS number 7761-88-8
Molecular weight AgNO3 = 169.9
Assay > 99.8 %

Used with Sodium thiosulphate to produce a Silver thiosulphatesolution (STS) containing the ethylene inhibitor [Ag(S2O3)2]3-. Prepare a 0.1 M Sodium thiosulphate stock solution by dissolving 1.58 g of Sodium thiosulphate into 100 ml of water. Prepare a 0.1 M Silver nitrate stock solution by dissolving 1.7 g of Silver nitrate into 100 ml of water. Store the stock solutions in the dark until needed to prepare the Silver thiosulphate solution (STS).In general the (STS) is prepared with a molar ratio between silver and thiosulphate of 1:4. Nearly all of the silver present in the solution is in the form of [Ag(S2O3)2]3-, the active complex for ethylene effect inhibition. Prepare a 0.02 M Silver thiosulphate solution (STS) by slowly pouring 20 ml of 0.1 M Silver nitrate stock solution into 80 ml of 0.1 M sodium thiosulphate stock solution. The Silver thiosulphate solution (STS) can be stored in the refrigerator for up to one month. However, preparation of the Silver thiosulphate solution (STS) just prior to use is recommended.
