What happens when magnesium ribbon is burnt in air? How will you test for its acidic/basic nature?
Answers
Explanation:
Magnesium burns in air to form Magnesium oxide (MgO). Take a moist red litmus paper and bring it in contact with the white ash of MgO. Red litmus paper turns blue. MgO is basic in nature.
When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. A compound is a material in which atoms of different elements are bonded to one another. Oxygen and magnesium combine in a chemical reaction to form this compound.
The main use of litmus is to test whether a solution is acidic or basic. Light Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under basic or alkaline conditions, with the color change occurring over the pH range 4.5–8.3 at 25 °C (77 °F). Neutral litmus paper is purple.
