Question

hydrogen peroxide is exposed to sunlight

Answer 1

When hydrogen peroxide exposed to sunlight a colourless,odourless gas is liberated which is oxygen and a liquid is produced which turns copper sulphate blue which is water

Answer 2

Answer:

Hydrogen peroxide decomposes when exposed to sunlight to give water and Oxygen.

Explanation:

Step 1 : Write down the formula of hydrogen peroxide.

The formula is given as :

H2O2

Hydrogen peroxide is a strong oxidizing agent.

When exposed to sunlight it readily decomposes by the UV rays to water and Oxygen.

Step 2 : Write down the equation for the decomposition of Hydrogen peroxide.

2H2O2(l) — UV rays —> 2 H2O(l) + O2 (g)

We therefore have our answer as :

The hydrogen peroxide in sunlight decomposes to form water and Oxygen.
