sodium cyanide solution

SODIUM CYANIDE SOLUTION CAMEO Chemicals NOAA

SODIUM CYANIDE SOLUTION is weakly basic. Reacts with acids of all kinds to generate quantities of very poisonous hydrogen cyanide gas. Incompatible with strong oxidizing agents, especially if solution dries out. Gives insoluble products with silver(I), mercury(I) and lead(II) ions that may decompose violently under certain conditions.

SODIUM CYANIDE : Systemic Agent CDC

May 12, 2011· Sodium cyanide is water-reactive. Sodium cyanide decomposes on contact with acids, acid salts, water, moisture, and carbon dioxide, producing highly toxic, flammable hydrogen cyanide gas. Sodium cyanide solution in water is a strong base; it reacts violently with acid and is corrosive. Sodium cyanide is incompatible with strong oxidants.

Cyanide Use in Gold Mining Earthworks

A sodium cyanide solution is commonly used to leach gold from ore. There are two types of leaching: Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. The cyanide dissolves the gold from the ore into the solution

Sodium cyanide — Sandvik Materials Technology

Sodium cyanide These corrosion data are mainly based on results of general corrosion laboratory tests,carried out with pure chemicals and water solutions nearly saturated with air (the corrosion rate can be quite different if the solution is free from oxygen).

What is the pH of 0.068M aqueous solution of sodium cyanide

Kb = [HA} [OH-] / [A-] where [A-] represents the concentration of CN-(.068M). Kb = Kw / Ka = 1 x10-14 / 4.9 x 10-10 = 2 x 10-5. Since this is a salt solution which could be considered to have formed from the neutralization of a strong base (NaOH) and a weak acid (HCN), the Na+ will have no effect on the pH of the solution while the CN- ion will undergo hydrolysis:

of sodium cyanide added correlated to the pH of the water is shown in Table 39.5. The aqueous solutions are strongly alkaline. At pH 9.4, in an aqueous solution of sodium cyanide, half of the total cyanide is present as hydrogen cyanide as in Eq. (39.6) (Ullmann’s, 1987). The toxicity of sodium cyanide on freshwater aquatic life is shown in
