This goes along with my thinking that it would be a great way to test CS. But I found that CS tends to stabilize H2O2 instead. Also I found that if you put silver metal into concentrated nitric acid, the reaction will be swift producing silver nitrate. But if you mix nitric acid with CS there is virtually no reaction unless you bring the temperature up to almost boiling. My take on this is that the reaction is mediated by a galvnaic current flow from impurities in the silver metal. IE. copper and silver have different potentials, so if there are any copper (or other impurity) atoms in a piece of silver, the "reactions" will take place, but the CS has so few atoms of copper or other impurities in it the majority of particles are pure silver, and thus do not react.
