1 of Can there be a variation in Chemica
composition of two psamples of pure was
taken from two different
places? Explain
Answers
Answer:
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:
NO, there will not be any variation in the chemical composition of two samples of pure water taken from two different places.
- The molecular formula of pure water is written as H2O.
- So whenever we are talking about pure water, it will mean that we are talking about H2O.
- If we take pure water from two different sources, its chemical composition will remain the same, i.e., H2O.
- Hence, the chemical composition is constant and it does not change with the source.
