00:01 Hi everyone in this question balance the redox reaction that occurs in acidic solution so we have given this ferrous ion plus bromate ion that will form ferric ion plus bromideon so let us find the oxidation number of these elements or ions so the oxidation number of f2 is plus 2 the oxidation number of bromine in bromate ion that is plus 5 and the oxidation number of oxygen here is minus 2 oxidation number of iron in ferric ion is plus 3 and oxidation number of bromine in bromide ion that is minus 1 so as you can see this is the redox reaction because this fe2 plus change to f e 3 plus that will increase in oxidation state and so increase in oxidation state means oxidation and in case of bromine here plus 5 2 minus 1 degrees in oxidation number so here in case of bromine we have reduction so let us divide this redox reaction into two equal two parts one is oxidation half reaction in short i can write it as ohr oxidation half reaction so oxidation can take place in case of iron so here f e 2 plus change to fe 3 plus so the oxidation number here is plus 2 and in f2 plus ion and here in f e 3 plus ion plus 3 so now balance this oxidation half for reaction as you can see the change in oxidation number is of 1 or we can see the here loss of 1 electron can take place so now this is the balanced equation balance oxidation half reaction so now let us see the reduction half reaction that is rh reduction half reaction.

02:14 So in case of reduction half, we have bromate ion that convert into bromide ion and the oxidation number of bromine in bromate is plus 5 and in bromide ion that is minus 1.

02:29 So let us balance the oxygen atom.

02:32 So in order to balance the oxygen atom, we have to add three water molecule in the right hand side of the reduction half reaction so that the oxygen atoms are balanced.

02:43 Now let us balance the hydrogen atoms.

02:45 So we have six hydrogen atom in the right hand side of the reduction half reaction.

02:51 So in order to balance the hydrogen atom, we have to add 6 h plus ion on the left hand side of the reduction half reaction.

03:02 So now we have to see the change.

03:05 So the change here can take place of the six electrons...
