The procedure of this test is simple as it involves introducing sample of the compound or element to a non-luminous, hot flame, and examining the color of the resulting flame.

Flame tests using metal salts | Resource | RSC Eduion

The colour of the light depends upon the metal (lithium(I) gives a magenta red-pink flame, calcium an orange red flame, potassium a lilac flame, strontium a crimson red flame, copper(II) gives a blue or green flame and sodium(I) gives a yellow flame). These colours are also often used in fireworks to give the different colours we see when they burn.

Flame Tests of Metal salts -

FLAME TEST AND ATOMIC SPECTRA LAB

Record the color and intensity (bright/faint) of the flame in the data table. The color given off by the salt is the initial color observed, not the yellow-orange color produced by the burning wood. (To avoid burning the wood, wave the splint through the flame rather than holding it right in the flame). Repeat with the other 8 salts.

Flame Tests - LanthanumK''s Blog

Jun 16, 2011· Later, an experiment similar to this will be done; only the later experiment is coustion and flame color, not just heating and flame color. A flame test can also be made by adding some of each salt to FancyHeat(R) methanol gel. The salt will dissolve in the gel and produce the respective flame color when the gel is ignited.

alkali metal | Definition, Properties, & Facts | Britannica

Alkali metal, any of the six elements of Group 1 (Ia) of the periodic table—lithium, sodium, potassium, rubidium, cesium, and francium. The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids).

Cobalt blue glass can be provided if available. The metal salt’s flame colour may be observed more easily when the yellow light is absorbed by the blue in the glass. Lithium – magenta red flame. Calcium - orange red flame. Potassium - lilac flame. Strontium – crimson red flame. Copper – blue or green flame (depends on the copper used)

Why do different metal salts produce different colors when

When metal salts are heated, electrons in the metal ions (or atoms) absorb heat energy and get promoted to higher energy levels. They are in an excited state. These electrons will jump back to their more stable (lower) energy level by emitting
