Why should a magnesium ribbon be cleaned before burning in air?

By Ritesh|Updated : November 4th, 2022

Magnesium ribbon should be cleaned before burning in air as it combines to form magnesium oxide with air. The metal magnesium is reactive. It forms a layer of magnesium oxide on its surface when it reacts with oxygen in the air. In order to remove the oxide coating that has formed on its surface, it should be cleaned with sand paper before burning.

Magnesium

  • Magnesium is the most chemically active element. In boiling water, magnesium replaces hydrogen, and many metals can be produced by thermal reduction of its salts and oxidized forms with magnesium. Magnesium is in the second group of the periodic table. I have.
  • We've been using magnesium in its bound form for 100 years, and it wasn't until chemist Sir Humphrey Davey washed and separated the metal. It took a very long time to isolate magnesium because it occurs naturally in a bound form. increase. It is the most common element in seawater.
  • It occurs in underground saline and salt formations. Magnesium is the third most common structural metal in the earth's crust after aluminum and iron.
  • Magnesium occurs naturally only in the form combined with other elements. The normal oxidation state of Mg is +2. Magnesium can be synthesized and many magnesium alloys are used in a variety of applications.

Uses of Magnesium

  • Magnesium is used by medical scientists. It is widely used to treat skin problems and attention deficit hyperactivity disorder (ADHD), anxiety, mania, recovery from surgery, etc.
  • Green leafy vegetables are an excellent source of magnesium. Whole grains, nuts and seeds are also good sources of magnesium.
  • Flush Valve also contains magnesium. When Mg burns, it offers a bright light which helps photographers take pictures in the dark.

Summary:

Why should a magnesium ribbon be cleaned before burning in air?

Before burning in air, magnesium ribbon needs to be cleaned since it reacts with the air to generate magnesium oxide. Mg plays an important role in the biochemical reactions that occur in our bodies. The main role of this ion in the body is to regulate the function of enzymes responsible for various chemical reactions.
