Potassium gives off a purple flame in a flame test due to the presence of potassium ions in the sample. When the sample is heated in a flame, the electrons in the potassium ions are excited to higher energy levels. As these electrons return to their original energy levels, they emit light in the visible spectrum, with the characteristic purple color being produced by potassium. This phenomenon is known as atomic emission spectroscopy and is used to identify the presence of specific elements in a sample based on the color of the flame produced.

A test that can be used to determine whether a solution has potassium sulfate?

To determine if a solution contains potassium sulfate, you can perform a flame test. When a sample of the solution is heated in a flame, the potassium ions will emit a lilac flame color, which is characteristic of potassium compounds. This can help confirm the presence of potassium sulfate in the solution.

What color flame test does the iodide solution give in flame test?

It is not the anions (e.g. iodide) that are responsible for the flame test color, rather the cations such as sodium ion, potassium ion and calcium ion give you different colors.
