The flame tests for sodium and potassium are based on the emissions at 589 nm and 404 nm, respectively. When both elements are present, the Na⁺ emission is so strong that the K⁺ emission can be seen only by looking through a cobalt-glass filter.
(a) What are the colors of these Na⁺ and K⁺ emissions?

Respuesta :

  • When the sodium ion is released, the flame test of sodium at 589 nm will display a golden yellow color. These are brought on by the alkali metal's electropositive properties.
  • When the potassium ion is released, the flame test for K at 404 nm will ignite a violet color.
  • These characteristics are a result of the group 1 element's high electropositive nature, which also indicates a strong reducing agent.

What is flame test?

  • An analytical technique called a flame test is used in chemistry to identify the presence of certain elements, primarily metal ions, based on each element's distinctive emission spectrum.
  • Temperature and oxygen supply also affect the general color of flames.
