What is Concentrated Solution: Define, Example & Diluted Solution

A concentrated solution is one in which there is a large amount of substance present in a mixture. A solution can be dilute or concentrated. A dilute solution is a solution that has very little solute in the solvent. Concentration is termed in a qualitative way through which the use of adjective such as dilute for solutions of relatively high in concentration. A dilute solution is one that contains a small amount of the solute in a given volume of solvent. Tap water is an example of a dilute solution; it contains very small quantities of dissolved minerals.

Examples of the concentrated solution:

Examples of the concentrated solution

  • Household strength bleach solutions can be 4% sodium hypochlorite and possibly some commercial strength bleach could be more concentrated.
  • The acid used for cleaning bricks for example to remove mortar that may have got on them in the process of bricking.
  • Brine is used for melting salt. It is a saturated solution of sodium chloride or common salt.
  • Battery acid is used in lead-acid cars it is the sulfuric acid.

Dilute solution example:

Dilute solution example

The water you ass the more dilute it gets. Vinegar is  5 percent acidic.

NaCl aq

H2SO4 aq




Unsaturated solutions:

Unsaturated solutions

Unsaturated solutions, to form them we need to add a solute to a solvent. The solute dissolves in a solvent and thus makes a constant solution.  A solution consists of particles, solutes and also the solvent. This solvent is a part of the solution which is usually liquid but can also be in the gaseous form sometimes. The water remains solvent most times.


Salt dissolved in water or even sugar dissolved in water is an unsaturated solution, if in case they dissolve more amount of solute in them. The gaseous solutions have gas as the solvent and the solute can either be in a solid state, liquid state or even gaseous state. Air, smoke, and mist are also the good examples of gaseous solutions.


The formula for a concentrated solution:

The formula for a concentrated solution

This is the amount of solute present in a given volume of solution. The concentration can be expressed in many different ways, such as moles per liter, mass per liter, or %. But most common solutions are given in morality (M), or “molar” [moles per liter].

How is concentration calculated?

How is concentration calculated

Once you’ve found the moles of solute, you can simply divide by the volume of solution in the flask to find the molarity of the solution, or convert moles to grams and divide by the volume of the solution to find the concentration in g/L. This will require a basic understanding of Stoichiometrymolarity.
