Solution+&+Suspension

Solution and Suspension Solution Definition of solution: A solute dissolves in a solvent to give a solution. Thus, it is a homogenous mixture in which one or more substances are dissolved in another substance. Definition of solute: A substance which dissolves in a liquid is called a solute. Definition of solvent: A liquid which dissolves in other substances is called a solvent. Do take note that 30cm­­3 of solute with 50cm3 of solvent is not equals to 80cm3 of solution as the particles of the solute are much smaller than that of the solvent. Thus, the solute particles take up the spaces between the solvent particles. A solution is formed when the solute particles surround the solvent particles. The particles will then intermix uniformly to form the solution. However, the solute and solvent particles do not combine chemically. Types of solutions · Solid – Liquid solution e.g. sugar solution, salt solution · Gas – Liquid solution e.g. hydrochloric acid, soft drinks · Solid – Solid solution e.g. brass, bronze · Liquid – Liquid solution e.g. vinegar, beer, wine · Gas – Gas solution e.g. air, natural gas Suspension Definition of suspension: A suspension is a mixture of small insoluble particles in a liquid or gas. Suspension is formed when a solid does not dissolve in a liquid. The solid is said to be insoluble. Examples of suspensions are calamine lotion, medicine and sea water. Suspension sometimes appears cloudy or chalky as some particles are so light that instead of sinking, they remain floating. Suspension can be separated by filtration because the solids are larger in size than the liquid particles and the holes in the filter paper. Differences between Suspension and Solution · A solution is homogenous while a suspension is not. · When a solution is being filtered, there are no residue particles left on the filter paper. However, when a suspension is filtered, the insoluble solids are left behind on the filter paper. · When a solution is left to stand, the solute does not separate from the solvent. When the suspension is left to stand, the insoluble solids settle to the bottom of the container. Dissolving For all solutions, there are limits to the amount of solute that can be dissolved in a given amount of solvent at a given temperature. The limit depends greatly on the solubility of the solute. There are a few factors that affect the extent of dissolving. They are: 1. Nature of solvent 2. Nature of solute 3. Temperature There are also factors that affect the rate of dissolving. They are: 1. Temperature 2. Rate of stirring 3. Size of solute particles Saturated Solution A saturated solution contains the maximum amount of solute that can dissolve in a fixed amount of solvent at a particular temperature. Solubility Definition of solubility: The solubility of a solute is the maximum amount of solute that can dissolve in 100g of solvent at a given temperature. The higher the solubility, the more soluble the substance. Concentration of Solution Definition of concentration: The concentration of a solution is the amount of solute in 1000cm3 of solution. A concentrated solution contains more solute particles in a fixed amount of solvent than a diluted solution. With that, I have come to the end of explaining Solution and Suspension. Relfection  After this lesson on solution and susupension, I now know the differences between the both terms. I also now how solutions are formed and some things that I should take note of, such as that when two substances are placed together, it need not be the volume of both added up together bacause the particles of the solvent has spaces in it and the particles of the solute may just fit into it, thus making the concept that two substances that is mixed together should have the volume of both stuff added up together before mixing.
