Question

Assertion: A solution is a homogeneous mixture of two or more substances. The major component of a solution is called the solvent, and the minor, the solute.
Reason:. The concentration of a solution is the amount of solute present per unit volume or per unit mass of the solution /. solvent.

Answer 1

ANSWER
Solute : It is that component of the solution, which is present in the smaller amount by weight in the solution.
Solvent : It is that component of the solution, which is present in the larger amount by weight in the solution. A solvent may be a liquid, solid, or gaseous substance that dissolves another solid, liquid, or gaseous solute, resulting in a solution that is soluble in a certain volume of solvent.
For e.g. In the figure shown below, some sugar is added in the water . So, solute is sugar and solvent is water here.

Answer 2

Both Assertion and Reason are true but Reason is not the correct explanation of the assertion.

SOLUTIONS -

• The homogeneous mixture formed by two or more substances.
• Particle size is less than 1 nanometre and does not show a scattering of light effect.
• The substance that is present in a small concentration is Solute.
• The solvent is the substance that is present in higher concentrations than the solute.
• Solution with low solute concentration is a dilute solution whereas if the solute concentration is high, the solution is a concentrated solution.
• The concentration of a solution is calculated as the measure of solute concentration in the given solvent.

                                                $Concentration = \frac{Solute amount }{Solvent concentration}$
