because it is an oil and has very low density i.e its lighter than water so it doesn't mixes with water but when you add vinegar to it, it will dissolve.
Petrol is insoluble in water because it is a nonpolar hydrocarbon. Water is a polar molecule, while petrol is nonpolar. This difference in polarity prevents the molecules from interacting and dissolving in each other.
Calcium carbonate (chalk) is only sparingly soluble in water. Being ionic, it is even less soluble in non-polar hydrocarbons like petrol.
Ionic compounds are held together by strong electrostatic forces between oppositely charged ions. When placed in a non-aqueous solvent like petrol which contains nonpolar molecules, these strong ionic bonds are not easily broken as the solvent cannot interact effectively with the ions. Therefore, ionic compounds are typically insoluble in non-aqueous solvents like petrol.
INSOLUBLE
Insoluble
non aqeous solvents like petrol and kerosine are having long carbon chains and both the end r having non polar groups generally. so there is no separation of charges in them to incorporate the ionic compounds in them........ answer 2...like dissolves like... ;)
Pepper is insoluble.
A substance that does not dissolve is insoluble.
This substance is insoluble in water.
Some collective nouns to use for petrol are a tank of petrol, a can of petrol, a container of petrol.
The antonym of soluble is insoluble. Something that is insoluble does not dissolve in a particular solvent.
insoluble... i think.. :/
