WAD* CYANIDE ANALYSIS Mintek

During titration the free cyanide in solution is consumed by Ag(NO)3 and a shift in the equilibrium results in some of the cyanides bound to metal species being liberated. This stretches out the endpoint of the cyanide concentration, and the titration over detects the presence of cyanide. This is especially problematic when there is a high copper

Use of ozone in the treatment of cyanide containing effluents

Considering that as long as cyanide is present in solution, no ozone is detected neither in the gas phase nor in the aqueous solution, it may be assumed that all the amount of ozone added is consumed by cyanide oxidation. By computing, the amount of oxidized cyanide and the added ozone, we find .

Solubility Product Constant University of Babylon

Solubility Product Constant In general, when ionic compounds dissolve in water, they go into solution as ions. When the solution becomes saturated with ions, that is, unable to hold any more, the excess solid settles to the bottom of the container and an equilibrium is established between the undissolved solid and the dissolved ions.
