Starting with our unbalanced redox reaction, we have as2o3 and no3 minus to h3aso4 and n2o3.
00:18
Break this apart into two half reactions.
00:21
We're going to need the major atoms arsenic and nitrogen.
00:24
First half reaction, as2o3 to h3aso4.
00:31
Two here to balance the arsenic.
00:33
That would give me eight oxygen on the right.
00:37
So i need 5h2o to balance.
00:40
10 hydrogen there.
00:42
There's already six, so four h plus and four electrons.
00:47
And then we have second half reaction, no3 minus to n2o3.
00:54
Two here.
00:56
And that would give me two nitrogens, six oxygens, 3h2o, 6h plus, four electrons.
01:09
Four electrons would cancel.
01:12
3h2o leaves me with two on the left.
01:15
H plus leaves me with two on the left...
