Q:

What is the definition of a "saturated solution"?

A:

Quick Answer

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.

Full Answer

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.

    What are the two parts of a solution?

    A:

    The two parts of a solution are the solvent and the solute. When the two parts combine to make a solution, the properties of the solution differ from the properties of the two individual parts.

  • Q:

    How many grams of KI are in 25.0 ml of a 3.0 percent KI solution?

    A:

    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.

  • Q:

    What does "solute" mean in science?

    A:

    A solute is the smaller part of a solution, which in many cases is said to have been dissolved by the solvent. A solution is any mixture that is homogeneous at a molecular level, which means that any given volume of the solution has about the same proportion of type of molecule in the overall solution as the overall solution.

  • Q:

    What is a non-aqueous solvent?

    A:

    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.
