The absolute purity doesn't exist; all the materials have impurities, less or more.
An impure substance can be called a mixture. It could be either heterogeneous mixture or homogeneous mixture.
If a substance in a mixture is preponderant--, if the amount far exceeds the amounts of the other substances in the mixture it is usually called an impure substance. Resource: Separation of the Components of a Mixture Lab -Chemistry
The melting point will be reduced because an impure substance is not held together as strongly as a pure substance therefore it takes less energy to break the bonds or attractive forces holding the impure substance together.
The melting point of an impure compound will become closer to that of the actual melting point of the pure substance with recrystallization of your mixture.
Sulphur can be pure or impure depending on it's source.For that matter no substance can be classified as pure or impure just by it's name.It depends on what chemists call ASSAY.Whenever you buy a chemical ask for ASSAY,you will know it's purity.Sometimes , even if the purity is not 100%,the chemical can be used if the impurity does not affect the product.Even the so called pure metals will have some amount of impurity
An impure substance contain impurities; for example polluted water is an impure substance.
impure substance
An impure substance contain impurities. The degree of purity depends on the desired application.
No.
No, it is not.
An impure substance can be called a mixture. It could be either heterogeneous mixture or homogeneous mixture.
impure because they are made of more than 1 substance
it depends on the substance

a mixture.
A substance might be pure with a single compound or impure with impurities along with principal compounds.
yes water is mixture of many impure substances and bacteria.even pure water has some bacterias.
