The addition of solute to a solvent concentrates the overall solution. A nice example is the laundry detergent. Some (less) concentrated detergents are less viscous, while highly concentrated detergents are more viscous (greater density). Also, adding more solute to a solvent can lower the freezing point.
We normally think of a solute as a solid that is added to a solvent (e.g., adding table salt to water), but the solute could just as easily exist in another phase. For example, if we add a small amount of ethanol to water, then the ethanol is the solute and the water is the solvent. If we add a smaller amount of water to a larger amount of ethanol, then the water could be the solute!
This statement is incorrect. If you add a solute to a solvent the total volume is not equal to the volume of the solute plus the volume of the solvent. This seems counterintuitive but when adding two different compounds together these compounds may stack together better or worse than they would separately. This can be seen very readily when mixing pure ethanol and water. It also results in the fact that using normal distillation methods you cannot get ethanol more pure than 95%. Hope that helps
The solution is said to be unsaturated. If the max amount is dissolved at a given temperature, then the solution is saturated.
If more solute is added to the solution and the solute remains undissolved, then you know that solution is saturated.
The solubility of a solvent increases as its temperature increases. Supersaturation is achieved by increasing the solubility of a solvent through temperature increase, saturating it with a solute, then lowering its temperature again, resulting in a solution that has more solute than it normally would at that temperature.
To make a solution you add a solute to a solvent.
To increase the concentration of a solution, you can decrease the amount of solvent by boiling off, or by evaporation, or you can simply add more solute. Conversely, to decrease the concentration, you can add more solvent.
You add more solvent.
You can eitheradd more solvent,allow some solvent to evaporate,add more solute,allow the solute to precipitate and remove some.
To create a more concentrated solution, you can add more solute (substance being dissolved) to the solvent (liquid medium). This increases the amount of solute particles in the solution, making it more concentrated. Alternatively, you can decrease the amount of solvent in the solution, which also increases the concentration of the solute.
Adding solvent will make a solution more diluted. Think of it this way. Take water (solvent) and dissolve salt into it (solute). In order to dilute or increase the ratio of solvent to solute, you would add more water.
Solution
When you add sugar (solute) into the tea (solvent) it mixes together to make a solution (when a solute/sugar, mixes into a solvent/tea.)The particles in the tea will start breaking up the sugar molecules. This is called dissolving, that is when a solute will mixes and disappear into a solvent.
If you add any more solute to the solvent it won't dissolve.
If no more solute can dissolve in a solvent, it means the solution is saturated. You can determine this by observing if there is excess solute at the bottom of the container that does not dissolve even with additional stirring. Another way is by conducting a solubility test, where you slowly add more solute to the solvent while stirring until it no longer dissolves.
A solution's concentration is a measure of solute/solvent. Solute is the thing to be mixed in (i.e. salt in salt water) and solvent is the medium, usually liquid, for the solute to be mixed in (i.e. the water in salt water). Therefore, increasing the ratio of solute to solvent would increase the concentration. This could be done by adding more solute, or removing the solvent (i.e. going back to the salt water, adding more salt, or evaporating water would increase the concentration) The converse of this is also true to decrease the concentration.
Increase the amount of solvent.
