Types of Solutions – Different Types, Homogeneous
A solution is a homogeneous mixture of two or more substances, consisting of atoms, ions or molecules. The compound that is present in largest amount in a homogeneous mixture is called the solvent, and others are solutes. For example, when a small amount of NaCl is dissolved in water, a homogeneous solution is obtained.
In this solution, Na+ and Cl– ions are uniformly distributed in water. Here water is the solvent as the amount of water is more compared to the amount of NaCl present in this solution, and NaCl is the solute.
The commonly used solutions are the solutions in which a solid solute is dissolved in a liquid solvent. However, solute or solvent can be in any of the three states of matter (solid, liquid, gas). If water is used as the solvent,the resultant solution is called as an aqueous solution. If solvents (Benzene, CCl4, ether etc.,) other than water is used, then the resultant solution is called as a nonaqueous solution.
The following table illustrates the different types of solutions based on the physical state of the solute and solvent.
Table 9.1 Types and Examples of Solutions
There are three types of solutions that can occur in your body based on solute concentration: isotonic, hypotonic, and hypertonic.
Solid – liquid:
A solid solute in a liquid solvent. Examples will be salt (solute) dissolved in water (solvent) and sugar (solute) dissolved in water (solvent).
Liquid – liquid:
A liquid solute in a liquid solvent.
Gas – liquid:
A gas solute in a liquid solvent.
Bleach (sodium hypochlorite dissolved in water) dishwater (soap dissolved in water) carbonated beverages (carbon dioxide dissolved in water is what gives sodas their fizz) powdered drinks.
These solutions have water as the solvent. Examples of such solutions are sugar in water, carbon dioxide in water, etc.
These solutions have a solvent that is not water.
Types of Solution:
A solution of two substances is called binary solution. In solution, the component that present in small amount is known as solute and the component present in larger amount known as solvent. Nine kinds of solution are possible.
Properties of a Solution:
Solutions are homogeneous mixtures of two or more substances whose components are uniformly distributed on a microscopic scale. The component present in the greatest amount is the solvent, and the components present in lesser amounts are the solute (s).
