Question

How will you show that metals form basic oxides?

Answer 1

Answer:

When metallic oxides react with water they form metallic hydroxides which are basic in nature.to show that these are basic in nature,we should conduct a litmus paper test.in this experiment,we will observe that red litmus turns blue on coming in contact with them. this shows that metallic oxides are basic in nature.

Answer 2

Answer:

Explanation:

because for acidity directly proportional to electronegativity

so basicity inversely proportional to electronegativity that means directly proportional to size

that means metals form basic oxides
