hydrocarbons are not soluble in a polar solvent but are soluble in a non-polar solvent.
They are practically insoluble.
Oil is hydrophobic because its chemical formula doesn't allow it to dissolve in water. In other words, it's "water hating".
The solubility of gas increases in cold water. The solubility of solid increases in hot water.
Like dissolves like. Hydrocarbons are non-polar, water is non-polar.
Strychnine solubility in water is 0,02 % at 20 oC.
The solubility of N in water is nil. N is the symbol for nitrogen and this gas does not dissolve in water. However nitrogen as a compound will have different solubility levels.
With a rise of temperature, the solubility increases
the solubility of the hydrocarbons decrease because as the number of carbons increase the electron density of the electronegative element i.e.oxygen increase and the polarity of o-H bond decrease . Thus the capability of hydrocarbon to form hydrogen bond decrease and its solubility decrease
Water is a polar solvent, hydrocarbons are not polar.
Although the solubility of most substances increases with temperature (eg you can dissolve more sugar in water when it is hot than you can in the same amount of water when it is cold) with gases the solubility decreases with temperature, so that cold water will hold more gas than the same amount of hot water. As oxygen is a gas its solubility decreases as the water temperature increases.
Oil is hydrophobic because its chemical formula doesn't allow it to dissolve in water. In other words, it's "water hating".
The solubility of gas increases in cold water. The solubility of solid increases in hot water.
As a general rule the solubility of solids in water or other solvents is improved raising the temperature.
Like dissolves like. Hydrocarbons are non-polar, water is non-polar.
Strychnine solubility in water is 0,02 % at 20 oC.
Hydrocarbons are non polar whereas water is polar. Therefore hydrocarbons do not dissolve in water.
The solubility of solid materials increase when the temperature increase; it is a general rule.
The solubility of a material in water is how much the object can absorb.
