SILVER NITRATE
מק"ט:
- 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.
- Storage condition
- Store at room temperature
- Soluble in water (2150 g/l / 20°C )
- Protect from light
