We are asked to balance this equation in acidic solution and let's begin.
00:05
First let's split these into our two half reactions and leave a little room here and go no3 and n2o3.
00:26
Okay so the first thing i'm going to do is balance my arsenic.
00:29
So i see i need to do my arsenic.
00:31
So now i have two arsenics on each side.
00:34
Then let's take a look at our oxygens.
00:36
I have eight oxygens so i will need to add number of waters here and i've got three so i have to add five waters onto this side.
00:57
This will give me ten and six so i have to add four hydrogens onto this side.
01:03
Let's see now.
01:04
So i have 10 h's and six 10 h's.
01:07
I have five six seven eight and eight.
01:11
Two arsenics and two arsenics.
01:13
Okay so that one's balanced except for my electrons and then taking a look at electrons here.
01:22
I've got four pluses so i will need four minuses.
01:26
Okay first half reaction done.
01:29
Second half reaction.
01:30
Let's start with the two here...
