<p>i feel retarded asking this, but it just isn't sinking in and i know i'm going to need it for the test</p>

<p>what exactly is normality and how do i calculate it?
in simplest terms. i've read about it everywhere and it still confuses me
i know it's equivalents/liter, and an equivalent is molarity x the number of equivalents..</p>

<p>i just need someone to break normality down in its simplest terms. it would be much appreciated. thank you.</p>

<p>edit: it'd even be more helpful with a balanced equation as an example :)</p>

<p>Normality is crap and you never need to know it for anything. Just multiply the molarity by the molar rxn coefficient for H.</p>

<p>yeah, i thought normality was useless too but then they brought it up with calculating volumes used in titrations, and i had been taught to calculate quantities in titrations in a different way, that's why is startled me</p>

<p>You need normality and not molarity in titration calculations because you have to balance equivalents.</p>
