How does density change with salinity?

Answer 1

The density of a solution will rise with the addition of more salt.

As more solute is added, the mass of the solution will increase much more significantly than the volume, leading to an increase in the mass/volume ratio and density.

If you put an egg in a glass of water, it will sink because the egg is denser than the water. However, if you mix in some salt, the solution's density will eventually rise above the egg's, causing the egg to float.

Higher salinities cause the water to become denser because they dissolve more salt, adding mass to the mixture.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
