effect of potassium cyanide on g metalsnov 02, · the discovery that metallic g is soluble in potassium cyanide came after studying the action of cyanides on plates of g, and announced that they were slowly dissolved. metallurgists pointed out that gleaf is dissolved by a dilute solution of the salt, and also showed that if the g floats on the surface of the liquid, so that one side of the leaf is in contact with the air, while the otherestimated reading time 9 minsbest alternatives to cyanide for suicide painless pathoct 09, · if you are familiar with chemicals, then you know cyanide is a rare but very deadly chemical. it kills you by disabling the body from using lifesustaining oxygen. some of the cyanide compounds that are toxic include potassium cyanide, hydrogen cyanide gas and sodium cyanide.warning
