Fluorine is highly reactive and can displace chlorine from sodium chloride to yield chlorine gas and sodium fluoride.
Complete the word equation for the displacement reaction that occurs when chlorine gas is bubbled through an aqueous solution of potassium iodide.
chlorine+potassium iodide→ \text{chlorine} + \text{potassium iodide} \rightarrow chlorine+potassium iodide→[blank] + [blank]
