Not to forget the equilibrium between calcium carbonate and calcium hydrogen carbonate.
CaCO3 + H2O + CO2 <=> Ca(HCO3)2
Hint: stalctite cave and Chalk in the coffeepot.

Re: Prominence of Redox reaction in organic chemistry
I would think about it, its the opposit Aluminium gets oxidiesdbejoy wrote:
An example for redox reaction is as follows:
2 Al +3 Br2 -> Al2Br6
In this reaction Bromine is been oxidized and Aluminum is being reduced
Al => Al3+ + 3 e-
Bromine gets reduced
Code: Select all
Br2 + 2 e-=> 2 Br-
