Mixtures

\r\nMixtures are physical combinations of pure substances that have no definite or constant composition the composition of a mixture varies according to who prepares the mixture.\r\n\r\nAlthough chemists have a difficult time separating compounds into their specific elements, the different parts of a mixture can be easily separated by physical means, such as filtration.\r\n\r\nFor example, suppose you have a mixture of salt and sand, and you want to purify the sand by removing the salt.
