What is the purpose of making sure that the outside of the magnesium strip is clean and shiny?
Homework Answers
Ans as magnesium is highly active metal upon interaction with air it formes oxides (MgO) or even small part reacts with nitrogen to form nitride and all these compounds creates ossue during the burning of magnesium so before doing any reaction with magnesium we clean it by sand paper
This oxidation of magnesium is just like rusting of iron however it form rust faster than Iron
