No refraction is the measure of the speed that the light travels through the substance, optical density is a measure of how much it is absorbed.

Basically. Light cant go through solid objects, or around it so it STOPS, then on the wall / behind the object there is a shadow casted.
Density -
High density --
More Movement more vibration's.
Low Density --
Less Movement Less Vibration's.

Very approximately, the greater the density the greater the refractive index (and therefore the slower the speed of light in that material).
This shouldn't be taken as a hard and fast rule; it's possible for two different materials of the same density to have different refractive indices and for two different materials with the same refractive index to have different densities.
If you're varying the density of the "water solution" by adding more solute, then sure; the concentration of solute will have an impact on the refractive index.
As Des said, you more or less can't vary the density of water to any significant degree under ordinary conditions (there's a whole field of engineering -- hydraulics -- that relies on this principle).
The refractive index is related to density; but because the density variations of water are very small the refractive index variations are not important.
yes
Optical density is the same in SI as in other system of units, since it is a dimensionless number. It is called the index of refraction, and can be defined as the speed of light in a vacuum divided by the speed of light in the material in question.Optical density is the same in SI as in other system of units, since it is a dimensionless number.

The ray of light bends towards the normal.
The amount of refraction depends on the difference in density between two mediums. So, the amount of refraction a material has, or it's refraction index, is the amount light will bend as it goes from medium into another medium. For instance, Vacuum is considered to have a refraction index of 1 and all other materials being denser than vacuum will naturally have a larger refraction index, they bend light more. So, it simply means that- since the object has a high density it will slow down light by a greater amount.
It will usually change. Usually you would expect the speed to decrease, but note that the "optical density", i.e. the index of refraction, is not entirely related to the density (as defined by mass/volume).
When a light ray is incident on a boundary of greater density than the current medium, the reflected ray undergoes a 180 degree phase change
Light does not refract via a single material. Refraction occurs when light passes from one material into another of a different density. It is the amount of difference in densities that causes the refraction. The greater the difference the greater the refraction. I believe that the densest material would be diamond, so light passing through a diamond and into a vacuum would seem to be the greatest difference, causing the greatest refraction.

It is called refraction, but some material bounces off the light and it is called reflection.

Refraction is what light does when it travels from one material to another. Refraction is when the light changes direction because it is passing through one medium to another.
The amount of refraction depends on the difference in density between two mediums. So, the amount of refraction a material has, or it's refraction index, is the amount light will bend as it goes from medium into another medium.
