To balance this reaction in basic solution, i'll use the half reaction technique and first balance it in acidic solution, after which i'll convert it to basic.
00:10
The first half reaction is bh4 - going to h2, bo3-.
00:20
We have one boron and one boron.
00:24
We next balance oxygens with water.
00:27
We have three oxygens and no oxygens, so we need to add three waters.
00:36
That gives us 6 hydrogens, which we add to this.
00:40
That's 10 hydrogens.
00:42
Over here we only have 2 hydrogens, so we need 8 more hydrogens, which we can add as h plus for now, assuming it's acidic.
00:51
Then we balance charges.
00:55
We need to add 8 electrons so that this side has a 1 minus charge and this side also has a 1 minus charge.
01:09
Then clo3 minus goes to cl minus.
01:19
The chlorines are balanced but the oxygens are not so we add 3h2o.
01:26
That then gives us 6 hydrogens so we add 6 h plus.
01:33
That gives us 6 plus charges minus 1...
