Why is lime used in gold mining?
Lime is used extensively in the recovery of gold and silver. Ores, either run of mine, milled, autoclaved, or roasted are combined with lime and a cyanide solution. The cyanide dissolves the gold and silver. Lime maintains proper pH in the cyanide solution keeping it in the liquid phase, preventing the formation of hydrogen cyanide gas and its loss into the atmosphere. hari julka
What the name of KCN?
Potassium Cyanide, because K is the symbol for Potassium and CN represents cyanide.
What is the name of the ion CN?
cyanide ionCannium (Cn)the polyatomic anion cyanide. compounds can be named such as Hydrogen Cyanide (HCN) and Sodium cyanide (NaCN)
Is sodium thiosulfate basic?
Sodium thiosulfate is not a base; it is a neutral compound with a pH close to 7. It is often used as an antidote for cyanide poisoning and as a fixer in photography.
What is the formula for silver cyanide?
The molecular formula for silver cyanide is AgCN.Silver cyanide is often used in silver plating.

What is the pH value of calcium cyanide?
Potassium iodide is neutral. So any solution of potassium iodide would have a pH of 7. One note: no substance has a particular pH as pH depends on both the acidity/basicity of a substance and how concentrated it is.
What would cause addition of KCN to water?
When potassium cyanide (KCN) is added to water, it dissociates into potassium ions (K+) and cyanide ions (CN-). These ions can then react with water molecules to form stable complexes, such as potassium cyanide ion or hydrocyanic acid, depending on the concentration and pH of the solution. This reaction releases cyanide ions, which can be highly toxic.

What is the formula for ammouium cyanide?
Ammonium cyanide is NH4CN
What is the formula for silver cyanide?
The molecular formula for silver cyanide is AgCN.Silver cyanide is often used in silver plating.
Does cyanide contain carbon?
Yes, cyanide contains carbon. Cyanide is a chemical compound composed of one carbon atom and one nitrogen atom, often found in the form of hydrogen cyanide or sodium cyanide.
You want to know manufacturing process of gold potassium cyanide electrolytically in detail?
Gold potassium cyanide is typically produced by electrolyzing a gold cyanide solution, where gold is electroplated onto a cathode. This process involves using a soluble anode made of gold and a cathode made of stainless steel or titanium. The electrolysis takes place in a specially designed cell containing the gold cyanide solution and requires strict control of parameters such as temperature, current density, and pH to ensure high-quality product formation. After the electrolysis is complete, the gold potassium cyanide is usually purified and then dried to obtain the final product.
Are cyanide and nitriles same?
Cyanide and nitriles can be grouped together. A nitrile is an organic compound that contains a cyanide (CN) group. However, other substances often called cyanide are not nitriles, including hydrogen cyanide, sodium cyanide, and potassium cyanide.
How much Cyanide is in sodium cyanide?
The formula of sodium cyanide is NaCN Therefore no. of moles of sample of NaCN is the same as that of the no. of moles of CN- ions
