Q:

Is water a Pure substance?

A) TRUE B) FALSE
Answer & Explanation Answer: A) TRUE

Explanation:

True, Water is a Pure substance and not a mixture.


 


We know that, A mixture is when two or more substances combine physically together. You can find that the mixture retains the properties of the original components.


In water, two hydrogen atoms combine with one oxygen atom chemically, forming a new substance that has properties different from hydrogen alone or oxygen alone.


 


Therefore, water is not a mixture; it is a compound and it is pure.
