Discuss the acidic and basic nature of the metals and non-metals with suitable experiments.
Answers
Explanation:
mgo +H20→H2co2. Non metals react with oxygen to form their oxides dissolve in water to form acids, when turn into blue litmus to red litmus. ex:c+o2→co2. co2+H2o →H2co2.
Answer:
Basic Nature of Metals
Procedure to follow to check the acidic nature of metals:
a) Take the small piece of magnesium in a test tube and burn it.
b) Add some distilled water to the remaining of magnesium left in the test tube.
c) Add red litmus paper to it. Note that color of it changes to blue.
Reaction: Mg + O2 → MgO
from this, we conclude that metals form basic oxides.
Acidic Nature of Non-metals
Steps to check the Acidic Nature of non-metals
a) Take a Deflagrating spoon (You can make it by wrapping
a thin wire around bottle cap.
b) Take a glass jar that has a lid on it.
c) Put some powdered sulphur in the spoon and heat it.
d) As soon as sulphur catches fire, insert the spoon into the glass jar and cover it with the lid.
e) Slowly remove the lid and pour some water into it.
f) Shake the glass jar and add blue litmus paper to it.
g) blue litmus paper changes to red which signifies the acidic nature of non-metals.
Reaction:
S + O2 → SO2
