And our first order of business is to write the overall net ionic equations for the reaction between iron three oxide and hydrochloric acid.
00:16
We're asked to write the complete and net net ionic equations.
00:22
So this will produce.
00:37
I did that backwards.
01:13
I just got a message i was looking at.
01:14
Sorry about that.
01:16
It's about my mother.
01:19
So this looks good.
01:21
There's my complete equation.
01:23
This will be an s and aq.
01:27
This is probably aq and this is l.
01:33
So my net ionic equation will include the species i'm going to highlight probably this, this, this doesn't fully dissociate, and this.
01:51
So my spectator ions will be the, oopsie, chlorides.
02:15
And that'll be what i do wrong here.
02:24
It'll be two fes plus three h2o's.
02:34
Okay.
02:37
Then we're asked to identify the bronze -dalori acid will be hcl because it is the h -plus donor.
02:59
And my bronze -dallory base will be my f .e .203 because it's a h -plus.
03:20
Sort of close enough b b hcl is also used to remove scale it reacts hcl reacts with calcium carbonate in two stages right equations for these two stages okay so the first forms bicarbonate so this stage forms a bicarbonate ion and let's see if i've got all my pieces here.
05:15
Okay, and then what happens? further reacts the bicarbonate ion, then further reacts, i'm assuming with hcl, to form co2 and then on cl minus and h2o.
05:50
And for the overall reaction.
05:54
So my overall reaction will be, that'll be c -a -2 plus my h -c -o.
06:20
That's gone.
06:22
C -a -c -l -2 plus h -2 plus c -o plus co2...
