Question

elect ALL the statements that are TRUE about a flame test. Note: You must select ALL the true statements to earn credit. Partial credit will not be given for partial answers. Be careful! Group of answer choices All metal cations will emit colors that are observable. The anion in an inorganic salt contributes to the color during the flame test. Different colors will have different wavelengths. The cation in an inorganic salt contributes to the color observed during the flame test. Some metal cations will emit colors that are observable.

Answer 1

Answer:

Ans) True , the electron of cation gets excited to higher energy level by absorbing energy and being unstable at excited state returns to the ground state by emitting energy whose wavelength happens to lie in visible region hence they show colour.

Explanation:

True , Different colours have different wavelength , In VIBGYOR , on going from violet to red the wavelength increases.

False, only those show colour whose emission wavelength of radiation lie in visible region.

True, some metal cations will emit colour that are observable

True, anion also contributes to the colour of salt in flame test. A given metal with different anion may give show different colours.
