A saturated solution is one in which any additional solute added to the solution is no longer dissolved. Solutions are combinations of solvents – most commonly liquids - and solutes, which are typically solids.Continue Reading
Each given solution has a point at which any more solute added does not dissolve. A prime example of this is demonstrated by adding sugar or salt to a glass of water. There is a point when any more of the solid added to the liquid results in the solid remaining in the bottom of the glass. This is, however, dependent upon temperature; most solutions show an increased saturation point in response to increased heat for a given pressure. In the most basic terms, an increase in heat results in more solute dissolving within the solvent.
Solutes are also commonly gases, as with the oxygen in water. Even with water, there is a point at which no more oxygen is dissolved. This is when the additional oxygen introduced into the solution is released as bubbles. Most gas solutions respond to heat and pressure in the same manner as solids, with warmer air absorbing more water vapor than cooler air, as is the case in one common example.Learn more about Solutions & Mixtures
A solvent is a substance that dissolves a solute in the formation of a solution, and any solvent other than water is considered a non-aqueous solvent. Some common examples include ether, alcohol, benzene, disulphide, carbon tetrachloride and acetone. While water is a useful solvent for investigating acid-base properties, the differences between water and other solvents mean that non-aqueous solvents often provide more realistic experimental outcomes.Full Answer >
A non-volatile solute has a low tendency to escape as vapor from a solution. Its vapor pressure is less than the vapor pressure of the solvent.Full Answer >
Assuming that a 3 percent solution represents a mass of solute in grams per volume of solution, there are 0.75 grams of KI in 25 mL of solution. However, the term percent solution is ambiguous; it can represent ratios of mass/mass, mass/volume or volume/volume.Full Answer >
A solution is saturated if there is visible solute that is not dissolving in the solution. Additional solute added to an already saturated solution just forms a layer of solute separate from the rest of the solution, according to a chemistry lesson posted by Mountain Empire Community College.Full Answer >
