Okay, so the equation you wrote down was kind of off.
00:05
I think you had some typos in there.
00:07
So i'm guessing that this is what you meant, i'm hoping.
00:10
So we have our lead going from plus 4 and oxygen is minus 2.
00:17
H is plus 1.
00:19
Cl is minus 1.
00:21
Goes to a 0.
00:22
Here it's minus 1.
00:24
Here this is plus 2.
00:26
Plus 1 and minus 2.
00:28
Okay, so we are going to do a redox reaction here.
00:33
The thing that's being reduced is our lead.
00:36
It goes from 4 to 2, and our chlorine or chloride ion is turning into chlorine.
00:44
So i'm going to balance this in an acidic solution because i can, because it didn't signify otherwise.
00:52
Otherwise, so pbo2 goes to pbcl2, and we had four, sorry, it doesn't look like it's over that, went from a four to a two.
01:09
I have the same number of pb's on each side, so i'm going to add two electrons to the left...
