We need to ensure that there are an equal number of each type of atom on both sides of the equation. Let's balance it step by step:
1. Balance the sulfur atoms:
There are 1 sulfur atom on the left side and 2 sulfur atoms on the right side. To balance sulfur, we need to put a coefficient of 2 in front of NaHSO3 on the left side:
H2SO4 + 2NaHSO3 = Na2SO4 + 2SO2 + 2H2O
2. Balance the sodium atoms:
Now, we have 2 sodium atoms on the left side and 2 sodium atoms on the right side. Sodium is already balanced.
3. Balance the oxygen atoms:
On the left side, we have 4 oxygen atoms from H2SO4 and 6 oxygen atoms from NaHSO3, making a total of 10 oxygen atoms. On the right side, we have 4 oxygen atoms from Na2SO4 and 4 oxygen atoms from 2H2O, making a total of 8 oxygen atoms.
To balance the oxygen atoms, we need to add a coefficient of 5/2 (which is the same as 2.5) in front of H2SO4 on the left side:
5/2H2SO4 + 2NaHSO3 = Na2SO4 + 2SO2 + 2H2O
4. Now, all the atoms are balanced.
The balanced chemical equation is:
5/2H2SO4 + 2NaHSO3 = Na2SO4 + 2SO2 + 2H2O
Please note that chemical equations with fractional coefficients like 5/2 are sometimes left as such, but in practice, you can multiply through by 2 to make it a whole number coefficient:
