Question

A concentrated solution contains a high amount of solute.
A. True
B. False

Answer 1

Think about the definition of a concentrated solution and think about the relation of the solvent and the solute in such a solution. This will give you an idea about the amount of solute that is required for a solution to be called concentrated. Concentration of any solution depends on the amount of solute, volume of solvent, and temperature.

Complete step by step solution:
Before looking at the definition of a concentrated solution, let us first look at what the concentration of a solution means. From that we will be able to identify the degrees of concentration and thus determine if concentrated solutions will have a high amount of solute particles. The concentration of a solution can be thought about as the amount of solute particles that are dissolved in a certain amount of solvent. Some units used to measure the concentration of a solution are molarity, normality, molality, parts per million, etc. According to the number of particles present in the solvent, we can determine the degree of concentration of the solution. When a solution has a relatively very small amount of solute particles dissolved in it, it is called a dilute solution. If the amount of solute in the solvent is relatively huge, then the solution is called concentrated. A solution becomes saturated when no further solute can be dissolved in the solvent at that temperature and it is supersaturated when no further solute can be dissolved after rigorous heating.

From these definitions we can safely say that a concentrated solution contains a large amount of solute particles.

Note: Remember that these are not the only degrees of concentration of solutions and they do not have rigid boundaries, it is a broad range of concentrations that can be called dilute or concentrated. Saturated solutions on the other hand have a fixed differentiation point.
