Assertion : Pure water obtained from different sources such as, river,...
And Reason are true and Reason is the correct explanation of the Assertion.

The assertion states that pure water obtained from different sources always contains hydrogen and oxygen combined in the ratio 1:8 by mass. This means that for every 1 gram of hydrogen, there will be 8 grams of oxygen in pure water.

The reason given is that a chemical compound always contains elements combined together in the same proportion by mass, as discovered by French chemist Joseph Proust.

This reason is indeed correct and provides an explanation for the assertion. Joseph Proust's discovery, known as the Law of Definite Proportions, states that a given compound always contains the same elements in the same proportions by mass. In the case of water, the ratio of hydrogen to oxygen is always 1:8, regardless of the source.

Therefore, both the assertion and reason are true, and the reason correctly explains the assertion.
