Lithium chloride solution most likely shows a vivid colour.
Answer: Option D
Explanation:
Flame test, an analytical strategy in chemistry to find certain elements, like metal ions, on the basis of characteristic emission spectrum of each element.
Because each element has a well-defined spectrum of linear emission, scientists can recognise it by the colour of the flame they produce.
For example, lithium and strontium red flame, nickel chloride appears as a brown or green solid, the potassium salt in the flame gives a characteristic purple colour, and hydrogen chloride as acid, a colourless gas. Colour's dense in the order as blue > red > green > yellow.
