The constituents of a mixture are not present in a fixed ratio. Ocean water in some regions is saltier than in others. The amount of carbon dioxide and water vapour present in air also varies from place to place.
Below you can find useful information on an experiment to separate a mixture of water and alcohol by the process of distillation. Take a mixture of water and alcohol in the distillation flask. Connect the flask to the receiver, that is, a conical flask. Adjust the apparatus firmly on stands.
Mixtures differ from compounds as follows: A mixture is heterogeneous, except solutions which are homogeneous whereas a chemical compound is always homogeneous.
A mixture is that form of matter in which two or more substances (elements or compounds) are present in any proportion. A mixture may be homogeneous or heterogeneous depending upon the substances present therein.
