Which is a chemical property that can be used to identify hydrogen peroxide? a. clear and colorless b. reacts when its exposed to light c. boiling point of 108 °c (226.4 °f) d. melting point of -33 °c (–27.4 °f)

Option (B) is the correct answer.

Explanation:

A property which tends to bring changes in chemical composition of a substance is known as chemical property.

For example, precipitation, reactivity, toxicity etc are chemical property.

So, when hydrogen peroxide reacts upon exposure to light then it depicts its chemical property.

On the other hand, a property that does not bring any change in chemical composition of a substance are known as physical properties.

For example, shape, size, mass, volume, density, etc of a substance are all physical properties.

Thus, we can conclude that a chemical property that can be used to identify hydrogen peroxide is that it reacts when its exposed to light.
