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).

When alkyl halide react with kCN form cynide but alkyle halide react with AgCN form iso cynide why?
in Agcn Ag is linked with the n of cyanide but in case of kcn kis linked with the c of cn
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
Is KCN broth selective?
yes
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.
Why kcn is inorganic?
because it exists as K+ and CN-
When alkyl halide react with kCN form cynide but alkyle halide react with AgCN form iso cynide why?
in Agcn Ag is linked with the n of cyanide but in case of kcn kis linked with the c of cn
What number of mole is KCN?
The answer will depend on the quantity of KCN.
Silver chloride often used in silver plating contains 75.27 percent Ag Calculate the mass of silver chloride required to plate 285mg of pure silver?
o.206 grams
What would cause addition of KCN to water?
Since potassium cyanide (KCN) is highly poisonous, the addition of KCN to water might be caused by an intention to kill.
How fast KCN kills human?
KCN kills a human being in 0.5 second.
CuSO4 reacts with KCN to give what?
CuSO4 + KCN --->Cu(CN)2 + K2SO4
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 is the meaning of Ag as used in titles such as Ag Head IT department?
Acting Head of department
What is the purpose of plating out cultures?
Plating can be used for resist the rust & corrosion.
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 year was chrome plating first used?
Chrome plating was first used on Model Ts in the 1920s.
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.
