Question

how does metal react with oxygen what is the effect of the product on Litmus Paper write to equation​

Answer 1

Answer:

Metal oxides are generally basic in nature.

When metal oxides react with acid they form respective metal salt and water.

Acid + Metal Oxide => Salt + Water

Neutralization Reaction :

1.4KB/s 4G+

4.0

Acid + Base => Salt + Water

This is similar to neutralization reaction where base comes instead of Metal oxide. Hence it can be concluded that Metal oxide is a base.

So Bases generally turn Red litmus to blue.

Hence the solution of any metal oxide will turn Red litmus to Blue but it has no effect on the Blue Litmus paper.
