flame test can be used to detect the presence of metal ions in a solution. The color of the flame of each ion depends on the atomic spectrum of the element. When you observe a violet color from your flame test, which ion is likely present in the tested solution?

Potassium ion

Explanation:

The answer is potassium ion.

The use of flame test is to detect the presence of metal ions in the solution. Different metal ions exhibits different colors when they are put into flames.

Sodium ion when subjected to fire or flame produces yellow flame.

Calcium ions and lithium ions produces red flames.

Potassium ions produces violet or purple flames when put to fire.

The color of the flame of each ion depends on the atomic spectrum of the element.

Thus the answer is Potassium ion.
