I just figured how annoying normality is. To get the full picture, I want to gather the names of as many solutions that have the same molarity, but different normality depending on the reaction they are used.
So far, I could think of Fe+3
ion, which could react to form either Fe+2
, thus having at least two normalities and one molarity. Same with copper.
The other one is H2
: One could
treat is as an usual acid or base (two acid/base sites per molecule), or use it for a typical complexometric titration (one complex is formed by one molecule). This gives at least two normalities and one molarity.
But I am sure there are examples I can't even think of. That's when all of you come in.
