What is the general rule regarding solubility of polar and non-polar substances?

"Like dissolves like"
This is simply stating that a solute will dissolve best in a solvent that has a similar polarity to itself.
For example, a very polar (hydrophilic) solute such as NaCl is very soluble in highly polar water and and practically insoluble in non-polar solvents such as benzene. However, a non-polar (lipophilic) solute such as carbon dioxide is insoluble in water and highly soluble in non-polar benzene.
For a non-polar solute such as carbon dioxide to become more soluble in water, the pressure of the system would have to be increased. This is why most sodas are under 5 atmospheres of pressure.

Are polar and non polar liquids soluble?
Generally not. The general rule to go by is like dissolves like. Polar substance will dissolve other polar substances while nonpolar substances will dissolve other nonpolar substances.
What one of these defines the like dissolves like rule of solubility?
As a general rule polar compounds are soluble in polar solvents and nonpolar compounds are soluble in nonpolar solvents.
Are lipids water soluable?
The lipids are a large and diverse group of naturally occurring organic compounds that are related by their solubility in nonpolar organic solvents (e.g. ether, chloroform, acetone & benzene) and general insolubility in water.
What is the general guideline for the prediction of solubility?
There is no ONE general guideline for predicting solubility. There are, however, a list of rules which can be consulted to predict the solubility of most compounds. One example of these rules can be found at the Chemwiki site.
Is a dipole polar or nonpolar?
Nonpolar compounds do not have dipole moments. Dipole moments are polar forces. If the compound is nonpolar then there is no polarity within that molecule.
How does the solubility of a substance change with a rise in temperature?
With a rise of temperature, the solubility increases
Does the temperature affects the solubility?
Yes, it does. In general, liquids and solids solubility will increase with temperature. The opposite for gases
What substances that do not dissolve easily in water?
you know water is a polar substance and can solve only polar substances and ionic substance it is not able to solve fat , oil or other organic (usually) substances (oil). by ionic substance I meant substances such as salt
Why does the solubility of gases increase in liquids on increassing the temperature?
It doesn't. In general solubility of gases decrease as temperature increases.
Is CH3-CH2-CHO soluble in water?
I would replace that word 'most' with 'totally' ... ethanol and water mix in all proportions.
What happens to the solubility of a solid in water as the temperature increases?
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.
What is the general relationship between solubility of a substance and temperature?
As the temperature increases the solubility also increases.
