Answer:
The reaction between cobalt (II) iodide (CoI2) and potassium acetate (CH3COOK) is a double replacement or double displacement reaction.
In a double replacement reaction, the cations and anions of two different compounds switch places to form new compounds. In this case, the cobalt cation (Co2+) from cobalt (II) iodide and the potassium cation (K+) from potassium acetate will combine to form potassium cobalt (II) iodide (KCoI3), while the iodide anion (I-) from cobalt (II) iodide will combine with the acetate anion (CH3COO-) from potassium acetate to form sodium iodide (NaI) and potassium acetate (CH3COOK).
The balanced chemical equation for this reaction can be written as:
CoI2 + CH3COOK → KCoI3 + CH3COOK
In summary, the reaction between cobalt (II) iodide and potassium acetate is a double replacement reaction where new compounds, potassium cobalt (II) iodide and sodium acetate, are formed
