Question

Can there be a variation in chemical composition of two samples of pure water taken from two different places explain

Answer 1

Yes, the composition may vary

Explanation:

• When we talk about the chemical composition fo water, it is not only about hydrogen and oxygen.

• Water is a combination of many chemicals and minerals like Chloride ions, sodium, calcium, magnesium, zic, copper etc.

• When we take water from two different lcations the chemical composition may vary depending upon the source of water

• Such as water taken from sea is more saline e.g. it has more salt content in it than water taken from river or lake

• Similarly, water taken from ground has different components in it than surface water

Answer 2

NO, there will not be any variation in the chemical composition of two samples of pure water taken from two different places.

-  The formula of pure water can be represented as H2O.

- It implies that whenever we talk about pure water, then we are talking about H2O.

- If pure water is taken from two different places then the chemical composition of it will remain the same, i.e., H2O.

- Hence, the chemical composition of water (H2O) is constant and it doesn't change with the source.
