Adding salt in water changes the buoyancy of plain water because the salt makes the water denser. This shows when an egg is place in water with salt, it floats, while with plain water, the egg sinks.

∙ 13y agoSalt increases buoyancy in water by dissolving in the water and making it more dense, allowing the water to hold up heavier objects than if it were pure.
This follows from the basic law which is that the upthrust on an object in a fluid is equal to the weight of fluid displaced.

∙ 15y agoThe buoyancy of a fluid is proportional to its density. Saltwater is about 2.5% more dense then fresh water so its bouyant force will be 2.5% larger. So if the bouyant force on an object in fresh water is 100 lbs it will be 102.5 lbs in saltwater

∙ 15y agoThe denser a liquid, the more buoyancy it provides for an object. You will float higher when swimming in salt water than in fresh water because salt water is denser.

∙ 15y agoThe amount of salt in water effects buoyancy (i.e.) the more salt in the water the denser the water the better any object floats in it.

How does adding salt to water effect evaporation?
The salt added to water makes the water colder so salt water evaporates slower than just plain fresh water.
Is adding of calcium to water a chemical change?
Yes, adding calcium to water is a chemical change. The following equation represents the reaction between calcium and water. Ca + 2H2O ---> Ca(OH)2 + H2
Does adding water change the pH of a base?
Yes. Ph is a measurement of the concentration of the hydronium ion [H+]. If you add more water you change the concentration.
Does water change color after adding charcoal?
Yes. In chemistry class we had to purify a water sample which was a-color. By adding charcoal and letting it sit over night, it went clear.
If you add sugar to water and put a chalk inside will it dissolve?
No. Chalk is insoluble in water. Adding sugar will not change that.
What affect provided by water aerobics helps make the exercise beneficial?
Buoyancy
What is the function of the ballast tanks on a submarine?
To change the buoyancy of the boat and allow it to rise and sink in the water.
Why does plain water boil faster than vinegar water?
Adding vinegar to water the effect of boiling point elevation occur.
Will a swimmer gain or lose buoyant force as she swims deeper in the water?
If she is completely immersed, there would only be a change if the water changes density (unlikely) or she changes her volume (also unlikely) as the buoyancy force is the product of her volume under the water, the density of the fluid and gravitational acceleration. If none of those change, then the buoyancy force will not change.
How does buoyancy affects a boat?
Buoyancy affects a boat by keeping it "on" the water, not "under" the water.
Is adding hot water to pot noodles a physical change?
Adding hot water to pot noodle is a physical change because the chemical nature of water remain unchanged.
Are Personal Floation Divcess more buoyant in deep water?
No the depth of the water does not change buoyancy. Floating in salt water is easier than in freshwater.
How does salt reduce buoyancy in water?
Salt actually increases buoyancy.
What are facts about buoyancy?
buoyancy has to deal with density, gravity, air, and water
Is adding starch in water chemical change?
Yes
Does buoyancy have anything to do with your human body being able to absorb water?
no, buoyancy is when something floats on water
Is adding calcium to water a chemical property or chemical change?
Calcium reacting with water is a chemical change.
