The main observations while performing the experiment of burning magnesium ribbon in air are : (i) Magnesium ribbon burns with a dazzling white flame. (ii) A white powder is formed. (iii) Magnesium ribbon vapourises. (iv) Aqueous solution of the white powder turns blue litmus to red.
Explanation
The correct options are (i) Magnesium ribbon burns with a dazzling white flame and (iv) Aqueous solution of the white powder turns blue litmus to red. This is because magnesium burns in air to form magnesium oxide, which is a white powder. The aqueous solution of magnesium oxide turns blue litmus to red due to its basic nature.
