Question

you are provided with magnesium ribbon and sulphur powder. explain with the help of an activity that metal oxides are basic and non metal oxides are acidic in nature

Answer 1

first of all will burn both a magnesium ribbon and the sulphur


then we will mix the oxides with water


then we will do litmus test on both the solutions

thwn we will observe that

sulphur oxide in water will turn blue litmus red and magnesium oxide will turn red litmus blue


this shows that metal oxides are basic and non metal oxides are acidic in nature

Answer 2

OBSERVATION : Have a magnesium ribbon in your hands . start the burner, now hold the tip of the ribbon next to the flame of the burner (by the help of holding tongs ). The ribbon burns with a dazzling bright light frame in order to produce the ashes and also intense heat is produced in this reaction. Now mix the collected ashes with water , it forms magnesium hydroxide . It's then tested with the litmus paper. over the red litmus change to blue This identifies that metallic oxides are basic in nature
