What happens if you mix...


What happens if you mix...

Salt + baking soda, Ammonia + bleach, Copper + carbon dioxide.

I'm obviously not going to mix ammonia + bleach or experiment with any those, but is there anything significant to the set above? I'm trying to make sense of a forum post I read.

Thanks :)

I wouldn't class Cu + CO2 with the other two, but I'm a chemistry plebian.

The first two are acid-base goodness, the second one would probably result in the oxidation of the Cu.

I'm not sure if CO2 will oxidize copper at any temperature. I suppose it might up around the melting point. The alternative being, will CO reduce CuO or Cu2O at any other temperature?

Salt is a neutral salt, so it doesn't react with any other sodium compounds.

I take it you are already aware of ammonia and bleach's hazardous reaction.

As for all three together, they seem to have no particular connection, aside from being rather uneducated combinations.
