Is iodide and potassium iodide the same?

Answer 1

NO, they are different.

Iodide is only one ion (I-) and potassium iodide (KI) is the salty product when you react potassium (K) and iodine (I2)

Answer 2

No, iodide refers to the ion I-, whereas potassium iodide is a chemical compound made up of both potassium (K+) and iodide ions (I-). When iodide is combined with potassium as in potassium iodide, the resulting compound has different properties and uses compared to just iodide alone.
