look up "buffer solutions", in particular the way CO2 will disolve in 
carbonate solutions. Also the way O2 / Fe / P interact in sea water.

Also look up the formation of Ammonia (NH3) from N2 + H2 + heat + presure, 
in particular consider a closed system and the way the equilibrium shifts 
giving more or less NH3 in the system.

You might also like to look at copper / ammonia complexes that absorbe 
carbon monoxide
