question 3: how does adding more water to an unsaturated solution affect its concentration? your prediction (check one): continuing to add water to an unsaturated solution will result in an increase in the concentration. continuing to add water to an unsaturated solution will result in a decrease in the concentration. continuing to add water to an unsaturated solution will result in no change to the concentration. experiment: add some solid potassium dichromate to .5 l of water. make sure the solution is not saturated. if it is, remove the solute and try again. what is the concentration? now, add enough water to bring the volume up to 1 l. observe changes to the concentration. conclusion: how does adding more water to an unsaturated solution affect its concentration?

Answer

Explanation:

Step1: Recall concentration formula

Concentration ($C$) = $\frac{n}{V}$, where $n$ is the amount of solute and $V$ is the volume of the solution.

Step2: Analyze adding water

When more water is added to an unsaturated solution, the volume $V$ of the solution increases while the amount of solute $n$ remains the same.

Step3: Determine concentration change

Since $C=\frac{n}{V}$ and $n$ is constant and $V$ increases, the value of $C$ decreases.

Answer:

Continuing to add water to an unsaturated solution will result in a decrease in the concentration.
