Can Salt Change Water's Density
Can salt change water’s density? I conducted an experiment using common household items to find an answer to my question. The procedure involves filling two cups with two hundred fifty milliliters of water. Then, mixing teaspoons of salt in water one at a time, until you’re able to submerge a raw egg in the solution and have it float up. My hypothesis is, salt does infact change water’s density, and if the egg floats it’s proof of density change in the water, because it must be less dense than the solution in order to float.

The procedure is as follows, I filled two cups with two hundred fifty milliliters of water and mixed four teaspoons of salt in one of the cups. Next, I placed an egg in both cups, the cup that did not receive the salt,

    If you put an egg in tap water, it will sink to the bottom. If you add enough salt, the egg will float to the surface. Density is the mass or volume of an object. It’s easier to think of it as the thickness of the object. Buoyancy is the force that allows an object to float. I performed a fun experiment to see how increasing density of water could make an egg float or submerge. Anyone can do it.…

    Research: Internet research shows that adding salt to water increases the density, and in turn makes it easier for objects to float. 4-10 teaspoons of salt in 1 glass of water is said to be enough to make one egg float (depending on the size of the glass). Multiple sources confirm this answer. Researching the topic also provides reasons as to why an object may float in water with higher density.…

    When trying to make an object float it depends on its density. Density is the “mass per unit volume.”[7] An object floats if it has less density then water. Objects like a boat floats because it has many parts that are filled with things that are less dense then water like air. When you add salt to the water the water becomes more dense allowing different objects to float. The salt dissolves into ions Na+ and Cl- which increases the mass of the water. The ions then link with the water molecules and then the molecules have a greater mass then the oxygen and hydrogen that the water is made of. Density is mass divided by volume and since there is now more mass the density of the water has also increased.…

    My hypothesis was that if the density of the sand-filled film container is less than the density of water, then the film container filled with sand will float. But, if the sand-filed container does not have less density than the water, then the container will sink. In this lab, this hypothesis was proven correct because all of the film containers with density less than 1 floated, and those with density greater than 1 sank. This experiment can be related to the real world if someone wanted to figure out how heavy and object could be and still stay afloat in water. A possible experimental error may have been if there was an error in weighing the film…
