Concepts of elements, compounds, atoms and molecules will add to the understanding of mixtures and solutions, alongside separation techniques. Solutions are homogenous mixtures: particles of one substance (the solute) are mixed together with the particles of another substance (the solvent) eg salty water. which feature does the scientist observe? Treatment with antacids alone is symptomatic and only justified for minor symptoms. The difference is that the composition of a pure substance is always the same, whereas two different homogenous mixtures made from similar molecules can have a different composition. The water can be collected through the process of condensation, whereas the sugar will be left remaining once the water has been completely boiled. Combining baking soda and vinegar causes a chemical reaction.

The individual components of a mixture can be physically separated from each other. First, you will need to heat to evaporate off most of the solvent from a solution to make a hot and nearly saturated solution. They mixed large amounts of sugar into the concrete, slowing down the setting process, and allowing them time to clear up the spill.
