Flame tests - lithium, sodium, potassium and copper (II) ions GCSE

All the GCSE flame tests demonstrated by me.

Lithium ions: red flame
sodium ions: yellow-orange flame
potassium ions: lilac flame
copper (II) ions: blue-green flame

My favorite example is having two containers next to each other (both containing methanol), and putting lithium chloride in one—for that gorgeous pink-tinged, deep red—and strontium chloride in the other—for its deep brick red.

They’re both gorgeous in their own right, but seeing them side by side makes you really appreciate the complexities of both colors.

1:54 i am not worrying about low light colour intensity of Potassium but i am worrying about because it also emitting bright yellow colour with purple i am doubting that is it because of Sodium impurity in the potassium or its secondary colour after pale purple ??

How to differentiate between calcium, strontium and lithium ion? All the three give red
