CBSE Class 10 Answered
Why should a magnesium ribbon be cleaned before burning in air ?
Asked by nadeemmohammad217 | 04 Feb, 2019, 03:45: PM
Expert Answer
Magnesium is a very reactive metal, so when usually exposed to air it reacts with oxygen and a layer of magnesium oxide is deposited on it.
It should be cleaned before burning to remove the oxide layer from it which may prevent or slow down the burning of magnesium ribbon.
