Explanation:
Now, a balanced equation of a reaction has equal atoms of each element on both sides. So we count the atoms each element.
-
We have
1 atom of Sulphur on the one side (SO_2 ) and1 on the other side (Na_2SO_3 ). -
We have
3 atoms of Oxygen on the one side (SO_2 andNaOH ), but4 on the other side (Na_2SO_3 andH_2O ). -
We have
1 atom of Sodium (NaOH ), but2 on the other side (Na_2SO_3 ). -
We have
1 atom of Hydrogen (NaOH ), but2 on the other side (H_2O ).
So to balance it:
