Tea is a mixture of one or more tasty oils dissolved in hot water. Is this a heterogeneous or homogeneous mixture? Are there any conditions under which this tea can be considered to be a pure substance? Explain. | |||||||||||

As long as the composition remains constant and uniform throughout, a homogeneous mixture can be treated as a pure substance. We call this a pseudo-component. | |||||||||||
