Because water is polar. Something that is non-polar doesn't dissolve in water because "like dissolves like."

Which gas least soluble in water?

You should specify the gases, by name, in your question. Otherwise, we are unable to answer.


Why iodine is more soluble in cl but less soluble in water?

Iodine is not soluble in water because iodine is nonpolar and water is polar. According to the "Like dissolve like" expression, nonpolar substances are soluble with nonpolar substances and polar substances are soluble with polar substances, but nonpolar substances are not soluble with polar substances.


Why salt is soluble in water?

Because sodium chloride and water are polar compounds.


Are kerosene and oil soluble?

No. Kerosene is an organic compound. and water is a non-organic compound. (kerosene : non-polar Water : polar). As water is a polar solvent kerosene is not soluble in it. but kerosene is soluble in ethyl alcohol which is a non-polar solvent.


Can gases cannot dissolve in water?

To find out the answer to this question, first you must understand about polarity. A polar molecule is one which has both: -polar bonds (ie. the intramolecular covalent molecular bond between both atoms are of different electronegativities, hence one gains a partially positive charge, delta +, and the more electronegative atom gains a partially negative charge, delta -). -the delta + and delta - centres to not coincide (and therefore do not cancel each other out) (need to know molecular structure to do this) Both of these mean that the molecule has an overall dipole (+ive and -ive side) Polar molecules are soluble (can dissolve) in other polar solvents. Non-polar molecules are soluble in other non-polar solvents. A polar substance is NOT soluble in a non-polar substance and vice versa. WATER IS A POLAR SUBSTANCE. Therefore, gases which are ALSO POLAR can dissolve in water.


How can you tell if material is soluble?

If a substance is polar, it is soluble in water.


Are polar molecules soluble in water?

No. Water is polar, and only dissolves other polar things.


Is HNO3 polar?

If its soluble in water it is polar so yes!


Is MgBr2 soluble or insoluble?

MgBr2 is soluble in water and other polar solvents.


Why are polar molecules soluble in water?

Polar molecules are soluble in water because water is a polar molecule itself. This means that water has a positive and negative end, allowing it to attract and surround other polar molecules, dissolving them easily.


What substance is not soluble in water?

actually in chemical bonding we discuss two type of compounds one is polar and one is non polar compounds. in both of these two only polar compounds are soluble in water and non polar compounds are not soluble in water and they are soluble in polar solvents like benzene and CCl4.


Is CsF soluble in water?

No, it is non-polar so it would not be soluble
