In simple terms, and for lack of a better description, let's say it depends on the amount of "active groups"
Explanation:
Let's take NaOH: this readily (and completely) disintegrates in water, and produces
If you have 1 Mol of NaOH and dissolve it in 1 litre of
Now consider the same with 1 Mol
This will dissolve into
BUT:
You now have twice as many
Also, we are dealing here with
Therefore, though you started with 1 Mol of
Could be a bit confusing, that's why Normality was introduced:
So:
a solution of 1 M
a solution of 1 M
Same of course goes for acids, where you take
Explanation:
For example, if you have 1 M sulphuric acid, in an acid/base reaction it would be 2 N ("twice normal"), due to each mole of sulphuric acid yielding 2 moles of
On the other hand, if you used 1 M sulphuric acid for something like precipitation of sulphates, then it would be 1 N ("normal") because each mole of sulphuric acid yields a mole of sulphate ions.
