A homogenous mixture of two or more different components in a relative amount having the particle size smaller than 1nm in the mixture is known as a solution in Chemistry. The term usually applies to the liquid state of matter, but solutions could even be of gases or solids. The air around us is an example of a solution that has oxygen in major amounts and nitrogen and other trace elements in smaller amounts. Alloys are an example of a solution in a solid-state.
Although a solution is a mixture of various substances, all the substances in a solution appear as a single phase. That is, a solution always has particle homogeneity. This also explains that all particles in the solution are evenly distributed. This can be explained with the following example- when you have a soft drink, the taste of the soft drink doesn’t change, it remains the same throughout the bottle, which describes the particle homogeneity of the solution.
In this article, we will learn what are solutions, the types of solutions, properties of solutions and so on. So, read on and explore all about solutions in Chemistry.
Characteristics of Solutions
A solution is a mixture of two or more different components. Out of these, one substance is always a component in which the other component dissolves. That is, one substance is a solvent and others are called solutes which dissolve in the solvent. So, the solvent is the substance which dissolves other substances in it, such as water. Water is also called the universal solvent because it dissolves most of the other particles in nature. The quantity of solvent is larger than the quantity of solute.
Solute, on the other hand, is the substance or component which is usually present in lower quantities than the solvent and it gets dissolved in the solvent.
Examples Of Solutions
1. Brass is an alloy of copper and zinc.
2. The air around us is an example of a gaseous form of solution.
3. Sugar syrup is a solution of sugar in water. Water is the solvent and sugar are the solutes in this case.
4. Coffee or tea is also an example of a solution.
5. Carbonated drinks are solutions of water as a solvent and carbon dioxide and other ingredients as solutes.
6. Tincture of iodine has alcohol as the solvent and iodine as the solute.
Types Of Solutions
Liquid solutions with water as the solvent are the most often found solutions around us. But gaseous and solid solutions are also quite abundant in nature. A solute or a solvent may be in any state of matter- gases, liquids, or solids. So, depending upon the physical state, solutions can be classified into various types.
