1. Salt, Sugar, and Methanol those samples are polar because they dissolve in water.
2. Wax, Acetone and Lighter Fluid those samples are non-polar because they don't dissolve in water.

From the data, i can conclude that Ethanol is less polar than water, because most of the samples when we added ethanol on them only one of the sample was soluble and the rest were insoluble.

I wouldn't expect ethanol to dissolve in water, and the same thing with hexane. After trying i conclude that Ethanol will dissolve in water. Hexane doesn't dissolve in water, water is a polar molecule, while hexane is a non-polar molecule " Like Dissolves Like".

• NH3

Type Of molecule: Polar Bond

Solubility in water:  Yes

Solubility in Hexane: No

• I2

Type of molecule: Non-Polar

Solubility in water: No

Solubility in Hexane: Yes

• HCL

Type of molecule: Polar Bond

Solubility in water: Yes

Solubility in Hexane: No

Ionic materials dissolve in water because the dipole characteristic of water molecules attract + and - ions pulling them apart/dissolving them. Hexane is a non-polar molecule so there's not that kind of attractions.

Enrichment:

Oxygen will not really dissolve, CO2 will dissolve a lot and Nitrogen electronegativity is less than Oxygen electronegativity which mean not a lot of Nitrogen will also dissolve. Aquatic animals such as fish  exchange oxygen and carbon dioxide across the land animals have flourished so well that in part, because they are able to take. Aquatic animals use oxygen that is already dissolved in the water around them.

Temperature, Surface area and stirring are factor that affect how fast something dissolves. The higher the temperature, the more particles will attract each other and the more there's going to be collisions between them, the substances will dissolve faster. Surface area does relate to this if you for example have something solid you break into pieces it will dissolve faster than living it as a big chunk and putting it in water.

Unsaturated means that a solution contain less solute than the saturated solution, the term saturated means the solution is holding as much solute it can have, the max, the term supersaturated means that the solution holding more than the max. The solution was saturated at 100 degree Celsius and the solution was unsaturated at 0 degree Celsius.

Enrichment:

Rock Candy is commonly formed by allowing a supersaturated solution of sugar and water to crystallize onto a string or some other surface suitable for crystal nucleation. Heating the water before adding the sugar allows more sugar to dissolve and thus produces larger crystals. Crystals form after several days. Food coloring is often added to the mixture to produce colored candy well as flavoring.
