Question

all of the following are true about the relationship between salt and fresh water except?
salt water floats on fresh water
higher salinity has a greater density than lower salinity water
the boiling point of water increases as salinity increases
the freezing point of water decreases as salinity increases

Explanation:

• Density: Salt water has higher density than fresh water. So, salt water sinks, not floats on fresh water.
• Boiling point: As salinity (salt content) increases, boiling point of water increases (due to colligative properties).
• Freezing point: As salinity increases, freezing point of water decreases (colligative property - freezing point depression).

Answer:

Salt water floats on fresh water
