  • Removing/freezing excess carbonate from cyanide

    The whole idea is to remove the carbonate from the silver plating bath. Potassium carbonate is fairly soluble in water (compared to sodium carbonate) so freezing out does not work. Materials such as calcium nitrate, barium cyanide, etc., will react with the potassium carbonate in the plating solution to give you a relatively insoluble carbonate.

  • What is the reaction between calcium cyanide and

    There should not be a reaction being that usually elements do not react with their nitrates. But if the calcium nitrate solution was acqueous (water), the calcium will react with the water and as I found in my class, turned black and appeared to react. It does not react with the nitrate but the solution's water.
