First, to answer this question, you must know that something floats when it is less dense than the liquid. Normally, an egg just barely sinks in in water, by adding salt to the water, it makes the water denser and thence changes its volume. It makes the water denser than the egg, which causes it to float on the water.
An egg floats in saltwater because the density of the saltwater is greater than the density of the egg. This causes the buoyant force acting on the egg to be greater than its weight, allowing it to float.
Dissolving salt into the water increases its
weight without appreciably changing it's volume.
Thus, the density (weight divided by volume) increases.
Something sinks when it weighs more than the
amount of water that it displaces. Conversely,
it floats when it weighs *less* than the water
it displaces.
An egg just barely sinks in pure water, but when
you add salt, the water becomes more dense and
the egg floats (since it is lighter than the
displaced amount of salt water).
If the concentration of the salt makes the water denser than the egg, the egg will float.
In less scientific terms :) :
The egg will float if there is enough salt.
Because salt allows air into the water in which the air reaches the egg and pushes it to the top of the water.
floating is only possible when the (mean) density of the solid is lower than the surrounding fluid it is immersed in.
Because of higher density, the buoyant force becomes more. Hence floating

Does tar float or sink in saltwater?
Tar is less dense than saltwater, so it will float on the surface of saltwater.
Will an egg float in one third salt water and two thirds water?
Yes, an egg will float in a solution of one-third salt water and two-thirds regular water because the increased density of the saltwater makes the egg less dense in comparison, causing it to float.
Why does an egg sink in water but float in salty water?
An egg sinks in regular water because it is more dense than water. When salt is added to water, it increases the water's density, making the egg less dense than the saltwater and causing it to float.
Do salt and sugar and flour make a egg float?
No, salt, sugar, and flour alone will not make an egg float. The density of an egg is higher than that of salt, sugar, and flour, so the egg will sink in these substances. However, if you were to dissolve a large amount of salt or sugar in water to create a solution with a higher density than the egg, then the egg could float in that solution.
Two identical corks float in separate beakers. One beaker contains distilled water. The other beaker contains a saltwater solution with a high concentration of salt. Which statement is true for this s?
The cork in the saltwater solution will float higher than the one in distilled water because saltwater is denser than freshwater, providing more buoyancy. The increased density of the saltwater displaces more water, helping the cork float higher.
Will an egg float in saltwater or freshwater?
SaltWater
Does an egg float on saltwater?
yes
Can an boiled egg float in saltwater?
yes, it can even float with heated water.
Who discovered how and egg can float on saltwater?
Probably a chicken.
What is the purpose saltwater making an egg float?
Saltwater is denser than freshwater, so when you add salt to water, the water becomes more dense. When you place an egg in saltwater, it floats because the density of the saltwater is higher than the density of the egg, causing it to float instead of sink.
Why will an egg float in saltwater other than freshwater?
cuz saltwater is more dense than freshwater
Why would egg float in saltwater and and not freshwater?
Eggs can float in saltwater because the high density of saltwater makes the overall density of the egg lower than that of the water, causing it to float. In freshwater, the egg is denser than the less dense water and therefore sinks.
Can a boiled egg float better in salt water or fresh water?
Because the density of the egg is lower than the density of the saltwater Because the density of the egg is lower than the density of the saltwater
What will float in saltwater but not float in tap water?
Objects that contain a higher density that water will sink, but if the same object has a lower density that saltwater, then it will float in salt water. And this also depends on the concentration of sodium ions present in the salt water. As the concentration of the sodium ions increase, the density of the salt water increases.
Does tar float or sink in saltwater?
Tar is less dense than saltwater, so it will float on the surface of saltwater.
How much salt can float an egg?
About 6 tablespoons - Check out the link below It depends on how old the egg is. An egg that is a week or so old will float in tap water...that's how you can test to see if an egg is fit to eat.
Will an egg float in one third salt water and two thirds water?
Yes, an egg will float in a solution of one-third salt water and two-thirds regular water because the increased density of the saltwater makes the egg less dense in comparison, causing it to float.
