This question says complete the table that follows with the proper ions, chemical formulas, and compound names.
00:07
The first three rows have been completed.
00:10
It doesn't say that all of these need to be acids, but i'm assuming that they are all supposed to be acids.
00:17
So the cation in every case is h -plus, which kind of makes it very redundant.
00:26
So i'll just start with the nitrite, the fourth row down.
00:37
And all of these are going to be h pluses.
00:41
And then we've got the anion, and they give it to us as n .o2 minus.
00:51
And they give us its name, nitrite.
01:02
And then they want the formula.
01:07
Nitrite has a one minus charge.
01:09
The h plus has a plus one charge, so we just need one of each of them.
01:16
And then they want the name of the compound.
01:22
The compound name for an acid, if it's an oxyacid, will not have the prefix hydro, and we'll just convert the it to us.
01:35
So this ends up being naitrus, and then we add the word acid.
01:44
And then for the next one, all they give us is the formula, hno3.
01:53
Which is this is nitrate with an additional oxygen, n -o -3 minus, and when it ends in 8, the 8 goes to ick.
02:11
So nitrate becomes nitric, and then we add the word acid.
02:19
And then for the next one, we've got c2h3o2 .2.
02:28
Minus, you should have that memorized as acetate.
02:33
So it'll be h, c2, h3, o2, just one of each of them, because we've got a minus one and a plus one...
