How to tát balance HCl+ BaSO3
The chemical reaction can be balanced using the following steps given below.
- If the number of atoms on the reactant side and product side is equal, then it is a balanced equation.
- HCl + BaSO3 ⟶ BaCl2 + SO2 +H2O.
- In the above reaction, on the reactant side, one atom of H, Cl, Ba, and S and three atoms of Oxygen is present, whereas on the product side, one atom of Ba and S and two atoms of H and Cl, whereas three atoms of Oxygen are present. It can be clear from the below table.
| Atom | Number of atoms on the reactant side | Number of atoms on the Product side |
|---|---|---|
| H | 1 | 2 |
| Cl | 1 | 3 |

| S | 1 | 1 |
| O | 3 | 3 |
- This reaction is unbalanced, which can be equalized by multiplying HCl by two on the reactant side ví the number of H and Cl on both sides will be equal.
- Finally, the balanced equation will be as follow.
- 2HCl + BaSO3 ⟶ BaCl2 + SO2 +H2O.
HCl + BaSO3 titration
As HCl is strong, the acid reacts with the base BaSO3 to tát give acid-base titration.
