Understanding Solution (Mixture) Concentration Problems

Solution concentration refers to the amount of solute (the substance being dissolved) present in a given quantity of solution. It is a measure of how “strong” or “weak” a solution is, based on the amount of dissolved substance (solute) relative to the solvent. Mathematically, concentration is typically expressed in terms of percentage:

\( \text{Concentration (%)} = \frac{\text{Amount of Solute}}{\text{Total Volume of Solution}} \times 100 \)

If you mix two solutions with different concentrations, you can calculate the resulting concentration using the following formula:

\( C_{\text{final}} = \frac{C_1 \times V_1 + C_2 \times V_2}{V_1 + V_2} \)

Where:

  • C1 and C2 are the concentrations of the two solutions.
  • V1 and V2 are the respective volumes of the solutions.

In this video, I explain the solution and mixture concentration in detail, along with some examples. Watch the entire video to fully grasp the concept. Additionally, there are quizzes based on this concept; you can find the link to the quizzes below.
