Give examples of solution

Answer 1

For most of us, the most familiar solution is that of solid in liquid; the most familiar of these are salt in water and sugar in water. As most of us know, common table salt is sodium chloride; its molecules consist of one sodium atom and one chlorine atom each. Sodium is so reactive that it is never found alone in nature, and chlorine is a poisonous gas; yet, when they are chemically combined, the form a substance that is to be found as a flavoring on the vast majority of dinner tables in the United states. Even when this salt is dissolved in water, it remains not only harmless (when used in amounts that improve the taste of food or drink without ruining either) but tasty, unless the concentration is too great. (Some people, of course, primarily those with edema, congestive heart failure, and hypertension, need to restrict their salt.) Salt ionizes in water, i.e. the chlorine in the compound takes on an electron from the sodium such that it has a charge--valence--of minus one, and the sodium acquires a plus one charge by giving up the electron. The charged particles, sodium and chloride, dissolve particularly well because they are attracted to the positive and negative ends of the polarized water molecule, wherein the end where the oxygen is attracts the sodium ions and the end where the hydrogen is attracts the chloride. The warmer the water, the more salt it will dissolve. In this case, the water is called the solvent, and the salt the solute.

Sometimes hot water will dissolve a huge amount of a substance, e.g. salt and sugar. One can make "simple syrup" by essentially filling a large mayonnaise jar with table sugar and pouring in as much hot water thereafter as possible. All of the sugar will be dissolved. Sugar does not ionize, but it still mixes with water in a way that both sugar and water mix with one another on a molecular basis. This is the definition of a solution; if there are any clumps of solvent or solute present in the mixture, it is not a true solution.

There are numerous other kinds of solutions. Gas can, for example, dissolve in liquid. Carbon dioxide, with each of its molecules consisting of one carbon atom and two oxygen atoms, dissolves in water, though warm water will not hold much of it. Unlike solid in liquid solutions, in the case of gas in liquid, the colder the liquid, the more solute it will dissolve. Thus, one notes that carbonated water is stable at cool temperatures, but, when it is warmed, it "fizzes."

There are many liquid in liquid solutions we can make. However, we tend to run into what are sort of philosophical problems when we do this. For instance, if one mixes ethyl or propyl alcohol in water, he is hard-pressed to say which liquid is the solvent and which is the solute. Therefore, some chemists say that such a mixture is just that, rather than a true solution. The same argument applies to a gas-gas solution.

Perhaps the strangest solution of all is solid in solid. The best example of this that I know is the mixture of carbon with iron to make steel. Of course, the steel must be melted in order that such a solution can be made; when it turns solid again, however, the solution remains intact.

Answer 2

The most commonly acknowledged solution in chemistry is salt water, but other examples include stuff like kool aid and whatnot.
