Final answer:

The correct representation of chlorine added to potassium iodide is D) Cl2 + KI, which results in the formation of potassium chloride and elemental iodine.

Step-by-step explanation:

When chlorine is added to potassium iodide (KI), the reaction can be represented by the chemical formula Cl2 + KI. So, the correct option that represents this reaction is D) Cl2 + KI. Chlorine, which is diatomic in its elemental form, reacts with potassium iodide to produce potassium chloride and elemental iodine according to the reaction:

2KI(aq) + Cl2(aq) → 2KCl(aq) + I2(g)

Through this reaction, iodine gas is freed, and if there is carbon tetrachloride (CCl4) present, it will turn purple, indicating the presence of iodine.
