Question

Double displacement reaction - write the balanced conventional, total ionic and net ionic equations:

Ca I2 (aq) + K2 C2 O4 (aq) >

Answer 1

See explanation.

Step-by-step explanation:

Hello!

In this case, these three equations show how the molecule behaves in terms aqueous and solid species; thus, we first write balanced conventional equation:

`Ca I_2 (aq) + K_2 C_2 O_4 (aq)\rightarrow CaC_2O_4(s)+2KI(aq)`

Whereas the solid product is CaC₂O₄ based off its low solubility. Next, we ionize the aqueous species to obtain the total ionic equation:

`Ca^(2+) +2I^- + 2K^+ +(C_2 O_4)^(2-) \rightarrow CaC_2O_4(s)+2I^- + 2K^+`

Finally, we cancel out potassium and iodide ions as they are the spectator ions due to their presence at both reactants and products in order to obtain the net ionic equation:

`Ca^(2+) (aq) +(C_2 O_4)^(2-)(aq) \rightarrow CaC_2O_4(s)`
