Nichrome is used because it is an alloy with a high melting point that will not affect the colour of the Bunsen flame. The slightly damp wire is then dipped into the unidentified powder. A blue Bunsen flame is needed and the colour change notice when the powder is placed in it should be noted.

Flame tests using metal salts- Learn Chemistry

Flame tests using metal salts Record the metal salt solution and the flame colour. 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).

Calcium | Ca - PubChem

Calcium plays a vital role in the anatomy, physiology and biochemistry of organisms and of the cell, particularly in signal transduction pathways. More than 500 human proteins are known to bind or transport calcium.The skeleton acts as a major mineral storage site for the element and releases Ca2+ ions into the bloodstream under controlled conditions.

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

Why Is Potassium Visible Through Cobalt Glass? | Reference

Why Is Potassium Visible Through Cobalt Glass? A potassium flame is visible through cobalt glass due to the color absorption properties of the blue glass. Cobalt glass absorbs the yellow color produced by sodium contamination in a sample, leaving only the purple light produced by potassium.

What component of the salts is responsible for the colours

Feb 20, 2010· Best Answer: Without knowing more about your class and the specifics of the salts, I would guess it would be transition metal centers. The energy gap between high and low energy D-orbitals in some transition metals in certain solutions will cause color to arise. Some classic examples would be: Copper(II

alkali metal | Definition, Properties, & Facts

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).

Color of chemicals - Wikipedia

The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. What is seen by the eye is not the color absorbed, but the complementary color from the removal of the absorbed wavelengths.
