  • How to Prepare and Storage of Cyanide Solution

    A special dissolving vat of small size is often provided and is placed at a higher level than the large vats used for the storage of the stock solution. High grade cyanide is now largely used containing 98 to 99 per cent, of KCy. Sodium cyanide is also used, and this, calculated as potassium cyanide, contains 125 to 130 per cent, of available KCy.Electrochemical preparation of potassium gold cyanide,depends on the purity of the gold salt used in the preparation of the bath. Be it an acid, neutral phosphate, citrate or alkaline cyanide gold plating bath, potassium gold cyanide (PGC) is the starting material. It is therefore important that pGc used for preparing plating baths must be very pure.

  • toxicity Why is potassium ferrocyanide considered safe

    $\begingroup$ @HRJ it is also worth noting that you need about 0.25g of pure potassium cyanide to kill an adult. This is a lot. Typical table salt contain maybe 10 micro grams of the ferrocyanide per gram. You would die far faster from excess table salt even if all the cyanide were released. $\endgroup$ matt_black Nov 6 at 14:26Iron in Cyanidation -Ferrocyanide Compounds,FERROUS CYANIDE Fe(CN)2: This complex may be regarded as ferrous ferrocyanide, Fe2Fe(CN)6, a polymer of Fe(CN)2.
