To balance the reaction in basic solution, i'll first balance it in acidic solution using the half reaction technique.
00:08
One reaction is with manganese, m2 +, going to mno4 - and the other half reaction is bio3 - minus, if with a sodium salt, well, it's a solid, so i guess we need to keep it together, nabio3 solid going to bi3 +, and sodium ion.
00:51
So first we balance everything but hydrogen and oxygen, one manganese, one manganese, one bismuth, one bismuth, one sodium, one sodium.
00:59
We then balance oxygens with water.
01:03
We've got four oxygens on the right -hand side, so we'll need four waters on the left -hand side.
01:09
We have three oxygens on the left -hand side, so we'll need three waters on the right -hand side.
01:16
Then we balance hydrogens with hydrogen ion.
01:21
We've got eight hydrogens, so we'll need 8h+.
01:25
We have 6 hydrogens, so we'll need 6h+.
01:30
Then we balance charges with electrons.
01:33
We have a 2 plus total charge, and we have a 7 plus total charge.
01:39
So that means we're going to need 5 electrons, so that this side becomes 2 plus just like this side.
01:49
This side has a 6 plus total and this has a 3 plus and a 1 plus so that's a 4 plus so we're going to need two electrons so both sides have a 4 plus...
