Question

How will you prove that Magnesium ribbon is basic in nature ?​

Answer 1

By doing litmus test and by burning the magnesium and making magnesium oxide and then do the litmus test of it and check is it acidic, basic or neutral

Answer 2

Answer:

To find the Magnesium ribbon is basic in nature . Let's perform an activity :

Activity -

Hold a magnesium ribbon with a pair of tongs and ignite (burn) it. Magnesium burns with a bright white light and forms a white powder . The white powder formed is Magnesium oxide

2Mg ( solid ) + O2 (gas ) --------- 2MGO

Collect this powder and dissolve it in water . Drip a strip of red litmus in the solution . The red litmus turns blue , indicating the solution is alkaline . This happens because Magnesium oxide dissolves in water to form Magnesium hydroxide ( which is alkali and hence turn red litmus blue )

MGO (S) + H2O (Liq.) ----- MG(OH)2 (dilute solution)

This activity shows that Magnesium ribbon in basic in nature .
