Solution (Solution) means the homogeneous mixture resulting from pure since 2 type to combine physical quantity of
.That is higher than a solvent (Solvent) that were less than a solute (Solute), as well as the solvent and the properties มีสถานะ borderline between substance source mixed. Solute particles smaller than 10-7 cm.Such as the solution of table salt, sugar solution, etc.!
call solution
.If the solution is water as a solvent, will begin with a "solution, followed by the name ถูกละ pattern, such as sodium chloride solution, acetic acid. If the solution contains a substance other than water as a solvent, to begin with. "Followed by the name, solute and solvent. "In accordance with such as chlorine solution in carbon tetrachloride solution of iodine in hexane Etc.
.
1 type of solution. A saturated solution (Saturated Solution) means the solution containing solute live fully. In one volume units of the solvent. And can't melt added again at a constant temperature
2.Unsaturated solution (Unsaturated Solution) means the solution containing solute. Melt is less than it should be dissolved. If the solute into. It would dissolve again without the temperature change is divided into
2.1) dilute solution (Dilute Solution) means of solute dissolved in a solution with low
2.2) solution concentration (Concentration. Solution) means the solution containing solute is very
1 criteria to break the solution.The state of the solution to the divided type is 3
1.1) solid solution means of melt with solvent is a solid state. Like brass, copper alloy, solder alloy, etc. 1
.2) solution liquid means solution containing solvent liquid status, such as syrup syrup, normal saline, fish sauce, vinegar. Soft drinks, etc.
1.3) solution gas means solution containing solvent is a state gas, such as air, gas cooker mothball in the air, steam in the air. Etc.
.Solute solvent used each kind is different. Depending on the relationship between solvent and solute, which both substances 2 type shall include homogeneous and no chemical reaction with each other. For example,
.- salt, sugar, food coloring, copper sulfate, alum, hydrochloric acid, sulfuric acid, using water as a
- foam, rubber, plastic, using gasoline as solvent
- Oil foam, plastic, lacquer, thinner solvent
.- oil turpentine as solvent
2. Use state of the solvent and the status of the solute เป็นเกณฑ์
3. Use the amount of solute in the solution concentration criterion
.The concentration of a solution is the quantity of the substance is dissolved, which dissolved in the aqueous solution.
1 per cent (percent) were divided into the following 1
.1)% by mass (w / W) indicates the mass of solute dissolved in the solution 100 unit such as solution concentration 10 linking by mass. Is in aqueous solutions 100 consists of sugar 10 welding G G
1.2) percent by volume (V / V) indicates the volume of a solute dissolved in a solution 100 volume units such as substance dissolve ethanol concentration 15 by volume. Is in aqueous ethanol 100 loop consisting of ethanol, 151.3) percentage by mass per volume (w / V) indicates the mass of solute in solution 100 volume units such as สารละลายเกลือแกง 100 cm (3). Containing salt 1 G
2. Ppt parts (part per thousand;Ppt) is a unit mass of solute concentration tell little dissolved in solution or solvent 1 A
3. Part per million (part per. Million;Ppm) is a unit mass of solute concentration said very little. Dissolved in solution or solvent 1 million parts (106 The) such as a fish mercury contamination in 0.2 ppm means in fish 1 million grams. A mercury 0.2 g
4.To tell the concentration based on quantity of solute in solution can be divided as follows:
4.1) solution, relative humidity, is a solution containing quantity melted. Dissolved in solution. Compared with solvent
4.2) dilute solution is a solution containing the solute dissolved in the solution is less. Compared with solvent
solubility has effect of
.At the same temperature and each kind of melt uneven. Depending on the factors as follows:
1. A kind of solvent type of solute 2.
, 3. In the case of solute pressure have the status of gas If the pressure increase will dissolve more
4.Solubility temperature of some kind increases when the temperature increase, but some types of melting less (out) when the temperature precipitation increase. As volume graphs solute with temperature
factors affecting the leaching effect of
1.A kind of solvent type of solute
2. 3. Pressure in the case of the solute is a state gas. If the pressure increase will dissolve more
4.? Temperature monitoring solution
1. Find pure boiling
