Video Transcript

Alright guys, so here we have to give the chemical formula for perchlorate ion. If you guys remember we have a system that names the halogens so its based on the number of oxygen's that are present. If you have 1 oxygen present then you have a prefix of hypo then you write the base word of the halogen and you have an ending of ite. Now if you have 2 oxygen's you just have an ending of it, if you have 3 oxygen's you have an ending of an ate and if you have 4 oxygen's you have a prefix of per then you write the base word of the halogen and you have an ending of an ate, so lets take a look.

Here we have per chlor ate, so per is the prefix, chlor is the base word of chlorine and ate is the ending. Which means we have 4 oxygen's present, right so this will be your perchlorate ion, lets move on.
