What happens to the amount of solute in a dilution process?
I - The amount of solute never changes in a dilution process.
II - Diluting something is decreasing its concentration by adding solvent to a more concentrated solution to obtain a new, less concentrated or more diluted solution.
III - The final amount of solute is always equal to the initial amount of solute in a dilution process.
a) Only I is correct.
b) Only II is correct.
c) Only III is correct.
d) I and II are correct.
e) II and III are correct.

A alternativa correta é a letra c) Only III is correct. No processo de diluição, a quantidade de soluto inicial é mantida, mas a concentração é reduzida pela adição de solvente. Portanto, a quantidade final de soluto é sempre igual à quantidade inicial de soluto. As alternativas I e II estão incorretas.
