Non-Chemical a way to stop a reaction

[goldnugget77]

I wanted to know if there is a way to stop a reaction
Lets say you have your gold clipping reacting with nitric acid
and all of a sudden you see that the blower is not working

I would guess if you could do it quickly and safely separate the acids from what you were dissolving. Pour the acids off into a clean vessel. Or use a mesh basket for your solids.

I did some work for a silver refiner once and he had an undersized scrubber so when we reacted the silver (always cast into bars) we just put the bars in a milk crate and lowered it into the nitric, the small surface area of the bars kept the reaction rate down so the scrubber would keep up and if it did run away the milk carton was lifted up out of the acid.

That would take forever.

Easiest way in my mind is to just add ice cubes or chill it. That'll slow it down at least.
