You may use this number in calculations but the results will be off.
I would suggest six for the other partner in the reaction as well. Notice that our difference is only VERBAL... I say 1 mol EDTA reacts with 1 mol calcium; corresponds to 6 N EDTA react with 6 N calicium (In that reaction; it's also 1:1). I am following a definition which won't affect the calculation cause in the very end they give the same result.
If we agree to call the Kg a "half-k" it won't be a problem at all with any calculation, as we generalize it...
For a complexation reaction, the reaction unit is the number of electron pairs that can be accepted by the metal or donated by the ligand.
That's the definition I got... Which goes for BOTH the EDTA and the one reacting with it. Of course, I don't mean that 6 N EDTA react with 2 N calcium (and I apologize if that what I managed to tell with my poor language). It goes for the donator AND the acceptor...
I asked the head of analytical chemistry department about this; how to calculate the normality of EDTA? she first told me that we don't need to calculate normality for EDTA as it reacts 1:1
then she said exactly what I stated
In this particular case it is molecule that is reacting unit
My friend, I don't mind this at all
but it needs to be a convention known somewhere (that's why I asked for a definition or reference). If there is a reference saying so, or a convention following so, I really don't mind
You know, it's like 7 years ago when I argued about the definition of a "meter" in a physics class. The instructor laughed and said: "Define any meter you like, but others use another definition
I am just afraid that conventionally the definition is different
Please understand that you can't use your references blindly, especially when they give simplified rules that contradict general definition.
Thanks for the advice. You might help me by giving me the general definition; may be I am mistaken. Please help me with this definition and mention the reference
This general definition, of course, should apply to all examples. It will really be helpful for me
Thanks a lot
