Explanation: A concentrated solution will contain the most solute molecules per solvent molecules. Hence, option D) is most concentrated.
Which of the following describes the term concentration?
In chemistry, concentration refers to the amount of a substance in a defined space. Another definition is that concentration is the ratio of solute in a solution to either solvent or total solution. Concentration is usually expressed in terms of mass per unit volume.
What is supersaturated solution give example?
A supersaturated solution is a more solute solution than can be dissolved by the solvent. If you haven’t learned what a solute / solvent is, the material that is dissolved in the solution, such as salts but not restricted to salts, is a solution. The most popular example is sodium acetate which is supersaturated.
What is true in a saturated solution?
What is true in a saturated solution is that it cannot dissolve any more solute. A saturated solution is a chemical solution that contains the highest concentration (maximum capacity) of a solute dissolved in the solvent. Examples of saturated solutions include; carbonated water and mixture of sugar and vinegar.
What is difference between saturated and unsaturated solution?
A saturated solution is a solution that contains the maximum amount of solute that is capable of being dissolved. At 20°C, the maximum amount of NaCl that will dissolve in 100. An unsaturated solution is a solution that contains less than the maximum amount of solute that is capable of being dissolved.
How do you know if a solution is unsaturated?
How can you tell if a solution is saturated or unsaturated? If more solute is added and it does not dissolve, then the original solution was saturated. If the added solute dissolves, then the original solution was unsaturated.
How will you prepare an unsaturated solution?
Stirring sugar or salt into water forms an unsaturated, saturated, or supersaturated solution, depending on how much sugar or salt (the solute) you add to the solvent (water). When you add a small amount of solute, all of it dissolves, forming an unsaturated solution.
What happens if a solute is added to a saturated solution?
You know you have a saturated solution as it will generally contain some undissolved solid solute. At this point adding more solute will not change the concentration of the solution; adding more solute will simply result in more solid at the bottom of the solution. A saturated solution is at equilibrium.
What are the advantages of preparing using solution?
3. The solution contains a homogeneous or uniform preparation which could provide a uniform dose or fixed value of components at a given dilution. 4. They are easily measurable if accurate measuring instruments are used.
How is the concentration of any solution expressed in terms of mass by volume percentage?
In case of a liquid dissolved in another liquid, percentage by mass has the same meaning but percentage by volume means the volume of the liquid solute in cm3 present in 100cm3 of the solution, i.e., it is volume/volume(w/v).
