Question

which of the following will decrease the concentration of a solution? select all that apply.
select all that apply:
□ adding more solute
□ adding more solvent
□ removing moles of solute
□ removing solvent by evaporation

Explanation:

The concentration of a solution is calculated as \( \text{Concentration}=\frac{\text{Moles of Solute}}{\text{Volume of Solution}} \).

• Adding more solute (\(n_{\text{solute}}\) increases) will increase the concentration.
• Adding more solvent (\(V_{\text{solution}}\) increases) will decrease the concentration.
• Removing moles of solute (\(n_{\text{solute}}\) decreases) will decrease the concentration.
• Removing solvent by evaporation (\(V_{\text{solution}}\) decreases) will increase the concentration.

Answer:

adding more solvent, removing moles of solute
