Question

Magnesium imparts: (1) Dazzling white colour flame Yellowish orange colour flame None of these Brick red colour flame

Answer 1

Option 1 is the correct answer,

i.e., Magnesium imparts dazzling white color flame while burning in air.

Explanation:

• Magnesium is burned to show how it burns by starting it .
• Bunsen flame and then removing it to watch it burn in the air with a brilliant white flame.
• White smoke is the end result.
• Burning the magnesium under an upside-down beaker will produce the result, which is a solid white ash called MgO (magnesium oxide), which may be collected.

Principle behind the work:

• The lightest structural metal is Magnesium (Mg), an alkaline-earth metal from Group 2 (IIa) of the periodic table.
• Magnesium is one of the elements required for all cellular life, and its derivatives are extensively used in both construction and medicine.
• Magnesium is a particularly chemically active element; it replaces hydrogen in boiling water and can be used in the thermic reduction of other elements to form many different metals.
• Most non-metals and practically all acids combine with it.
