PdCl₂ + 4 HNO₃ → Pd(NO₃)₂ + 2 NOCl + 2 H₂O
Here's a breakdown of the reaction:
* Reactants:
* PdCl₂: Palladium chloride is the starting palladium compound.
* HNO₃: Nitric acid is the oxidizing agent, which will react with palladium to form palladium nitrate.
* Products:
* Pd(NO₃)₂: Palladium nitrate is the desired product.
* NOCl: Nitrosyl chloride is a byproduct of the reaction.
* H₂O: Water is also produced as a byproduct.
Explanation of the balancing process:
1. Identify the atoms involved: The equation contains Pd, Cl, H, N, and O.
2. Balance the palladium (Pd): Both sides already have one Pd atom.
3. Balance the chlorine (Cl): There are two Cl atoms on the left side and two on the right side (in NOCl).
4. Balance the nitrogen (N): There are four N atoms on the left side (in HNO₃) and two on the right side (in Pd(NO₃)₂) and two in NOCl. To balance, add a coefficient of 2 to NOCl.
5. Balance the oxygen (O): There are twelve O atoms on the left side (four in HNO₃) and eight on the right side (six in Pd(NO₃)₂ and two in NOCl). To balance, add a coefficient of 2 to H₂O.
6. Balance the hydrogen (H): There are four H atoms on the left side (in HNO₃) and four on the right side (in H₂O).
This balanced equation reflects the stoichiometry of the reaction, ensuring that the same number of each type of atom appears on both sides of the equation.
