Normally AgCN but not KCN is used to reduce free cyanide in the plating bath from CN- to Ag(CN)2- in order to prevent cyanide immersion forming. Addition AgCN make the bath chemical equilibrium more stable as accumulation of free cyanide. There is no reason why KCN is used (CM Lew, Malaysia).

What is the formula for the compound that forms from potassium and cyanide?
To answer this you need a roman numeral on gold to know the charge on it. Assuming it would be (I)... the formula would be KAu(CN)2
Why haloalkanes gives cyano product with kcn and gives isocyano with agcn?
Haloalkanes react with KCN to form nitriles because CN- acts as a nucleophile attacking the carbon of the halogen atom, leading to substitution. On the other hand, with AgCN, the reaction proceeds through an isocyanide intermediate due to the ability of Ag+ to stabilize the cyanide ion, promoting nucleophilic addition to the carbon of the halogen atom.
Does 0.1 M KCN have a pH greater than 7.0?
Yes. Since KCN is a salt of strong base and weak acid,its water solution will be basic.Therefore,0.1M KCN have pH greater than 7,its pH is 11.
When alkyl halide react with kCN form cynide but alkyle halide react with AgCN form iso cynide why?
In the presence of potassium cyanide (KCN), alkyl halides typically undergo an SN2 reaction to form nitriles due to the strong nucleophilicity of cyanide ion. However, when reacting with silver cyanide (AgCN), the reaction mechanism favors an SN1 pathway due to the solubility of AgCN in polar solvents, resulting in the formation of isocyanides (also known as isonitriles) instead of nitriles.
What is plating equipment?
Plating equipment is used in the electroplating process to coat a surface with a thin layer of metal. This equipment typically includes a plating tank, power supply, electrodes, and a variety of chemicals depending on the specific plating process being used. It is essential for creating a durable and decorative metal finish on various products.
What number of mole is KCN?
The answer will depend on the quantity of KCN.
How fast KCN kills human?
KCN kills a human being in 0.5 second.
What is the formula for the compound that forms from potassium and cyanide?
To answer this you need a roman numeral on gold to know the charge on it. Assuming it would be (I)... the formula would be KAu(CN)2
What year was chrome plating first used?
Chrome plating was first used on Model Ts in the 1920s.
How do you prepare kcn?
We can prepare KCN by the reaction of KOH and HCN.Where HCN can be generated by the pyrolysis of formamide.
What is plastic chrome plating used for?
Plastic chrome plating is used a lot of time for car parts, like grills and the nameplates on the side. Basically, plastic chrome plating is used for taking plastic things and chrome plating them, like a trophy or the front of a car.
Why kcn bonding is through carbon and agcn bonding through nitrogen?
Because KCN is a ionic compound but AgCN is covalent compound . So, when KCN is dissolved the we get K+ ion and CN_ ion then bonding takes place through carbon but in AgCN doesn't give ions so bond formation takes place form free side of AgCN or from nitrogen.
Why haloalkanes gives cyano product with kcn and gives isocyano with agcn?
Haloalkanes react with KCN to form nitriles because CN- acts as a nucleophile attacking the carbon of the halogen atom, leading to substitution. On the other hand, with AgCN, the reaction proceeds through an isocyanide intermediate due to the ability of Ag+ to stabilize the cyanide ion, promoting nucleophilic addition to the carbon of the halogen atom.
What salt is poisonous?
Examples of poisonous salts: KCN, HgCl2, NaCN.
How does cyanide affect the environment during mining?
Cyanides (NaCN or KCN) are not used in uranium mining and recovery, but it is used in gold mining.
What type of plating was originally used on 1958 Rochester carburetors?
Platinium plating and some models rhodium.
What is barrel and rack electroplating?
Barrel plating usually used for singulated units. Current supplied to the units by means of "fingers"/tangler in the barrel. Rack plating usually used for matrix work piece. Workpiece need to be placed in the rack for plating. Both platings hv similar plating concept, but pysically the plating done differently.
