Production of silver cyanide from silver nitrate

For 107.868 grams of silver (169.87 grams of silver nitrate), it will require 65.12 grams of potassium cyanide. This will produce 133.84 grams of silver cyanide. This is assuming pure, dry chemicals and the total absence of nitric acid. Any excess of potassium cyanide will dissolve some of the silver cyanide …
