Why should a magnesium ribbon be cleaned before burning in air yeah?
Answers
Answer:
Magnesium is chemically very active, it takes the place of hydrogen in boiling water and a great number of metals can be produced by thermic reduction of its salts and oxidized forms with magnesium. Magnesium is labelled as the eighth most abundant element and about 2% of earth’s crust is constituted by Magnesium.
In seawater, it is the most plentiful element present. It is not only found in seawater but also in underground brines and salty layers. After aluminium and iron, magnesium is the third most abundant structural metal in the earth’s crust.
→ A magnesium ribbon should be cleaned before burning in air because magnesium when exposed to air reacts with oxygen which leads to the formation of magnesium oxide on the surface of magnesium ribbon.
