candybox14 - Salt added to water increases its density thereby acting on the buoyancy of any object placed in the liquid. Seawater is approximately 2.5% more dense than freshwater. It contains about 35 grams of salt (sodium chloride) per liter of water. A saturated saltwater mixture (the water cannot dissolve any more salt) contains about 350 grams of salt per liter of water and would increase the buoyancy significantly. There are several references you can find relating to buoyancy, saltwater density and Archimedes principle that might help you understand the effect. Good luck.
