Note:
(i) Tetraamminepalladium(II) sulphate is hygroscopic, hence the value quoted here will be subject to change upon opening the container for a period of time.
(ii) Tetraamminepalladium(II) sulphate produced is routinely checked for metallic impurities. Other metallic impurities are rarely found in our incoming palladium obtained from our supplier.
Weighing tolerance =  0.1gm
Turbidity of the solution is observed by visual inspection at a known concentration.
Shelf life of Pd(NH3)4SO4 is 12 months.
