Determine whether the following statement is true or false. If a substance seems to be uniform throughout then it must be pure.
Question
Determine whether the following statement is true or false. If a substance seems to be uniform throughout then it must be pure.
Solution
The statement is false. Just because a substance appears to be uniform throughout does not necessarily mean it is pure. It could be a homogeneous mixture, which appears uniform throughout but consists of different substances. A pure substance consists only of one type of atom or molecule. Therefore, appearance alone is not a reliable indicator of purity.
