Solution and suspension are mixture of two different substances (solute and solvent) that have different characteristics
A summary of the difference between solution and suspension is the following.
What is the solution?
A solution is the homogeneous mixture of two or more uniform comments and properties and evenly distributed. A true solution is the combination of two substances solute and solvent. A solute is the substance that is dissolve in solvent changes its state in forming the solution. It is present in excess concentration.
A Solvent is the substance that is able to dissolve other substance (solute). Both solute and solvent are in same phase of matter. The solution is cloudy in appearance and light can pass through the solution without getting scattered thus Tyndall effect (scattering of light) is absent in the solution
The solution can pass through easily from ordinary filter paper and also through the animal membrane and no residue left on the filter paper, but solute and solvent can’t be separated with ordinary filter or ultra-filtration. There is not Brownian effect or Brownian motion (random, uncontrolled movement of particles in the fluid) is not observed in the solution. An example of a solution is saltwater, sugar dissolved in water.
Types of solution
On the physical states of solvent and solute a solution can be categorized into three types
Solid solution
Both the solute and solvent are in solid state. Example of solid solution is crandy berry glass and brass (composed of zinc and copper) and steel (composed of carbon and iron)
Liquid solution
The solvent is liquid form in this type of solution. Example is salt water
Gaseous solutions
Homogeneous mixture of gases e.g. a hydrogen (solute) dissolved in palladium (solvent)
Depending upon the number of solutes in solution it can be
Dilute solution
A solution with small amount of solute in large concentration of solvent
Concentrated solution
A solution with large amount of solute in dissolved in a small amount of solvent.
Other types of solution are following
Supersaturated solution
A supersaturated solution is one where the solute is present in an excess amount and more than the average solvent can be dissolved at a given temperature
Unsaturated solution
A solution that contains less amount of solute or solute concentration is lower than its equilibrium solubility)
Saturated solution
A solution in which no more solute can be dissolved in the solvent at a definite temperature.
Aqueous solutions
The solution that contains water as the solvent e.g. sugar in water
Non-Aqueous Solutions
The solution that doesn’t contain water as a solvent. The solvent can be ether, benzene, petrol, carbon tetrachloride, etc. Examples of the non-aqueous solutions are liquid ammonia, liquid sulfur dioxide.
What is Suspension?
a suspension is a heterogeneous mixture of two or more substances in which the solid particles (size greater than 1000 nm)are spread throughout the liquid without dissolving in it and can be seen with naked eyes. Suspension can not be filtered with filter paper as it can not pass through the filter.
When filtered the insoluble particles are left as residue on filter paper. They are opaque and can’t pass light through them but if light pass them then they scatter a beam of light passing through them because of its large particle size. They show Tyndale effect
