When Magnesium ribbon is kept in added to a test tube of water, it does not react. However, when it is cleaned with sandpaper and added to an identical test tube of water it reacts rapidly. Why?
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.
