These concepts will be reinforced and contextualised at 1416, when students study materials such as crude oil and rock ores. The substance that does not dissolve is called the solvent. Any two pure samples have precisely the same uniform composition throughout. What relationship exists between a homogeneous mixture and the number of phases in the mixture? Both in everyday life and in the scientific field, mixtures that involve a solid element and another liquid are very common , usually the first acting as an element to be dissolved and the second as a space for dissolution. I am writing an essay and when I wanted to use this phrase I realised that I am not certain which one to use. While buying a bottle of liquor, a customer determines the potency of it by V/V or W/W label present on the bottle.
