In my Chemistry class, we had a total of 9 different compounds such as

1.Strontium Chloride 2. Copper Chloride 3. Potassium Iodine 4. Barium Chloride 5.Calcium Nitrate 6.Sodium Chloride 7.Sodium Iodine and then two unknowns.

We went through the first 6, and we listed the colors it produced when put into the flame. After experimenting with the first six we then did the two unknowns and noted the colors of them. We then compared the two unknowns with the first six of the list listed above. When the colors match, look at the first element in the compound such as Copper Chloride. Copper would be the element to produce the color.

All the unknowns have different chemical properties. So when they are burned to perform the flame test, they emit different colored flames. Based on the color of the flames, the unknown can be identified.

Why is it difficult to identify potassium ions and sodium ions in low sodium salt using a flame test?

When sodium is subjected to a flame test, it burns a bright yellow. This yellow flame can be brighter than the lilac flame color of the potassium, which makes it more difficult to distinguish between the sodium and potassium.
