Like dissolves like.
Water is an extremely polar solvent because of its ability to form hydrogen bonds with neighbouring water molecules (the partial negative of Oxygen is attracted to the partial positive charge on the hydrogen atoms). Therefore, if a substance dissolves readily in water, it would be polar.
Think of the inability to dissolve oil in water. Oil, a lipid, is a fatty acid hydrocarbon. Hydrocarbons are infamously nonpolar and would "repel" the polar water molecules.
Take note, however, that this is generalised notion. There are always exceptions, especially in a biological system, because slightly nonpolar molecules can end up dissolving in polar water.
What else can I help you with?
Do paraffin and water mix?
No, paraffin and water do not mix because paraffin is a nonpolar substance whereas water is a polar substance. Since like dissolves like, nonpolar substances like paraffin do not dissolve in polar substances like water.
Would a non polar molecule dissolve in a polar molecule?
Nonpolar molecules tend to dissolve better in other nonpolar molecules due to similar intermolecular forces, while polar molecules dissolve better in other polar molecules. This is because like dissolves like - molecules with similar polarity tend to mix well together. Generally, nonpolar molecules do not dissolve easily in polar solvents.
What is the substance that would not dissolve well in water and why?
Oil is a substance that does not dissolve well in water because oil molecules are hydrophobic, meaning they repel water molecules. This leads to a lack of interaction between oil and water molecules, making it difficult for them to mix together.
Should you try to dissolve a compound in water to determine if it is polar?
This method may work in certain cases, but many polar compounds are immiscible in water. An example would be fatty acids: polar by definition, but can be insoluble in H2O as their tail length increases
Would petroleum ether dissolve in vegetable oil?
Petroleum ether is a nonpolar solvent, while vegetable oil is a nonpolar substance. Since like dissolves like, petroleum ether should be able to dissolve in vegetable oil to some extent.
Do paraffin and water mix?
No, paraffin and water do not mix because paraffin is a nonpolar substance whereas water is a polar substance. Since like dissolves like, nonpolar substances like paraffin do not dissolve in polar substances like water.
Would a non polar molecule dissolve in a polar molecule?

How is water equipped to break the relatively powerful ionic bonds making up crystals like sodium chloride?
Because of the phrase "like dissolves like". Both NaCl and water are made up of polar bonds and have a polar shape, so like dissolves like. If NaCl was nonpolar in its shape, the polar water would not be able to dissolve the nonpolar NaCl.
Should you try to dissolve a compound in water to determine if it is polar?

Is sio4 polar or non polar?
No, SiH4 is not polar. It is nonpolar. It is considered nonpolar because it does not have permanent dipole moments.
Would petroleum ether dissolve in vegetable oil?
Petroleum ether is a nonpolar solvent, while vegetable oil is a nonpolar substance. Since like dissolves like, petroleum ether should be able to dissolve in vegetable oil to some extent.
Is wax a polar or non-polar molecule?
Parrafin wax is non-polar.
What would form a heterogenous mixture?
mixture of polar and nonpolar liquids.
What is meant by like in the solubility guideline like dissolves like?
There are basically two types of solvents, polar and non-polar. This refers to the electrical charges in a molecule; polar molecules have positive and negative poles, non-polar molecules don't. The most familiar polar solvent is water, familiar non-polar solvents would be such things as gasoline, cooking oil, etc. So, polar substances dissolve in polar solvents, and non-polar substances dissolve in non-polar solvents. A polar substance will not dissolve in a non-polar solvent. Soap is a chemical that has both polar and non-polar elements to its molecular composition, and therefore is able to bridge the gap between polar and non-polar.
What kind of particle would move through a cell membrane the easiest- small or large-polar or nonpolar?
Small and nonpolar.
Would ch3cl mix with h2o?
Yes, due to the fact that the C and CL have a non-polar relationship and H2O also is very non-polar. Like dissolves like, and you get your mix.
