Classification of reactions

  1. Apr 8, 2013 #1
    1. The problem statement, all variables and given/known data

    Hello,
    I'm trying to learn how to classify reactions. I want to know how do I tell ionization, self protolysis and hydrolysis.

    2. Relevant equations

    NH4(aq) + H20(l) <--> NH3(aq) + H30(aq)+ This is hydrolysis why? How does it differ from this hydrolysis.
    CO32-(aq) + H20(l) <--> HCO3-(aq) + OH-(aq) I don't understand.

    Can you please give me examples of how to classify each reaction asked about?
    Thanks
    j

    I would not call it hydrolysis, just dissociation. Produced proton attaches to the water molecule.

    Here water molecule is split into H+ and OH-.

    Trick is, hydrolysis means slightly different things in different contexts. On a general level hydrolysis means "decomposition by reaction with water". Apparently there is no compound decomposition in the case of dissociated carbonate - there is a reaction with water, in which it is water that decomposes.
