Q:

What is a concentrated solution?

A:

A concentrated solution is one in which there is a large amount of substance present in a mixture. The degree of concentration is measured in moles.

An aqueous solution contains at least two substances: the solvent, water and a solute — the matter that will be dissolved in the water. The amount of solute that is dissolved in a solvent is the concentration. To keep track of the concentration, you can keep track of the mass. However, many find it easier to measure liquids using molarity, which is the number of moles of solute in a solution divided by the volume of the solution in liters.

  • Q:

    How do you explain the difference between mixtures and solutions for kids?

    A:

    A precise but simple explanation of the difference between a mixture and a solution is that a mixture is a substance made of other substances that are mixed but not joined together, while a solution is a substance made of two or more substances that do join together. If the kids are older, it should be noted that a chemical reaction takes place to create a solution and that no such reaction occurs in a mixture.
