How do you balance #IrCl_3 + Ca(OH)_2 - Ir_2O_3 + HCl + CaCl_2#?

Question

How do you balance #IrCl_3 + Ca(OH)_2 -> Ir_2O_3 + HCl + CaCl_2#?

Peyton Adams · Accepted Answer

#2IrCl_3 + 3Ca(OH)_2 rarr Ir_2O_3 + 3CaCl_2 + 3H_2O#

As Ernest wrote, #HCl# will not result from the reaction. While the reaction product would be exceedingly difficult to characterize, an #Ir(OH)_3# species would probably precipitate to give a hydrous oxide of #Ir(III)#:

#Ir^(3+) + 3HO^(-) rarr 2Ir(OH)_3 rarr Ir_2O_3 + 3H_2O#

Naturally, collecting the entire solid would be necessary if you carried out this reaction. Iridium is not only a heavy metal but also a precious metal with a high gram value.

undefined The balanced chemical equation for the reaction between IrCl3 and Ca(OH)2 is:

2 IrCl3 + 3 Ca(OH)2 → Ir2O3 + 6 HCl + 3 CaCl2

undefined To balance the equation, follow these steps:

1. **Write the unbalanced equation**:
   $$ \text{IrCl}_3 + \text{Ca(OH)}_2 \rightarrow \text{Ir}_2\text{O}_3 + \text{HCl} + \text{CaCl}_2 $$

2. **Count atoms in reactants & products**:
   - Reactants:
     - Ir: 1
     - Cl: 3
     - Ca: 1
     - O: 2
     - H: 2
   - Products:
     - Ir: 2
     - Cl: 1 (in HCl) + 2 (in CaCl₂) = 3
     - Ca: 1
     - O: 3
     - H: 1

3. **Balance Iridium (Ir)**:
   - Put a 2 in front of IrCl₃.
   $$ 2 \text{IrCl}_3 + \text{Ca(OH)}_2 \rightarrow \text{Ir}_2\text{O}_3 + \text{HCl} + \text{CaCl}_2 $$

4. **Update counts**:
   - Ir: 2
   - Cl: 6
   - Ca: 1
   - O: 2
   - H: 2

5. **Balance Chlorine (Cl)**:
   - Put a 6 in front of HCl.
   $$ 2 \text{IrCl}_3 + \text{Ca(OH)}_2 \rightarrow \text{Ir}_2\text{O}_3 + 6 \text{HCl} + \text{CaCl}_2 $$

6. **Update counts again**:
   - Reactants:
     - Cl: 6
   - Products:
     - Cl: 2 (in CaCl₂) + 6 (in HCl) = 8 (error!)

7. **Recheck with balancing**:
   - Correct Coefficients:
   $$ 2 \text{IrCl}_3 + 3 \text{Ca(OH)}_2 \rightarrow \text{Ir}_2\text{O}_3 + 6 \text{HCl} + 3 \text{CaCl}_2 $$

8. **Final verification**:
   - Atoms in reactants:
     - Ir: 2, Cl: 6, Ca: 3, O: 6, H: 6
   - Atoms in products:
     - Ir: 2, Cl: 6, Ca: 3, O: 3, H: 6

Everything matches! The balanced equation is:
$$ 2 \text{IrCl}_3 + 3 \text{Ca(OH)}_2 \rightarrow \text{Ir}_2\text{O}_3 + 6 \text{HCl} + 3 \text{CaCl}_2 $$
