Three students are asked to discuss whether each dissolution performed in
lab had a decrease or increase in entropy. Select the student that employs
correct scientific reasoning.
• Student 1: The entropy increased for ammonium nitrate because more species were introduced
into water, while the entropy decreased for sodium hydroxide because hydroxide is already
present in water.
- Student 2: The entropy increased for ammonium nitrate and sodium hydroxide dissolution
reactions because dissolving always causes an increase in micro-states.
• Student 3: The entropy decreased for ammonium nitrate and sodium hydroxide dissolution
reactions because the salts became more ordered when they went into solution.
