Question

when diluting a solution, which of the following changes?
select all that apply:
solution volume
solution concentration
moles of solute
volume of solvent

Explanation:

When diluting a solution, more solvent is added. This increases the solution volume (since \(V_{solution}=V_{solute}+V_{solvent}\)). The concentration (\(C = \frac{n}{V}\), where \(n\) is moles of solute and \(V\) is solution volume) decreases because \(V\) increases while \(n\) (moles of solute) remains the same (no solute is added or removed during dilution). The volume of solvent increases as we add more solvent for dilution.

Answer:

solution volume, solution concentration, volume of solvent
