In fact, it undergoes spontaneous combustion in water, so while sodium is essential for human nutrition, you wouldn't want to eat pure sodium. A heterogeneous mixture contains particles of different shapes or sizes and the composition of one sample may differ from that of another sample. If the solute and the solvent are both liquids and soluble in any . There are, however, a few cases in which saltwater might become a heterogeneous mixture or might end up taking longer to become homogeneous. An opened can of soda is an example of a heterogeneous mixture. For example, you can make a homogeneous solution of sugar and water, but if there are crystals in the solution, it becomes a heterogeneous mixture. ), 15620 views Express your answer to three significant figures and include the appropriate units. Once this kind of mixture forms, you can no longer separate the individual ingredients again, thus ensuring that the mixture has now formed definitively and that all the substances are now uniformly distributed throughout. It is only when the water has other impurities or substances in it (as in the case of seawater), has a particularly insoluble kind of salt, has a cooler temperature or has become saturated that the mixture might lean towards becoming heterogeneous. It is a pure substance. When this happens salt is said to be dissolved in water and a homogeneous salt solution results. A heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture. It is a heterogeneous mixture. Salt (NaCl) is a pure substance because it contains two elements in a fixed ratio and has only one component.
