Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

The fact that ionic substances tend to dissolve in water is a big clue. Another one which is also great fun is the 'bending water' trick. You need a polythene rod and a fuzzy charging cloth, and a tap with a thin trickle of water coming from it. Charge up the rod then bring it near to the water stream,but not touching it, a few inches below the spout. You should be able to deflect the water stream so that it is pulled over towards the rod.
Thanks for the feedback!

Why is a water molecule polar?

Since oxygen is more electronegative than hydrogen, you get something called a "dipole moment," making the oxygen slightly negative because of the unequal sharing of electrons

Why is a water molecule a polar molecule?

Different elements have different electro-negativities. Electro-negativity is the ability of an atom to withdraw 'electron density' towards itself, i.e. it makes electrons com

How do polar molecules dissolve in water?

Dissolving is just when water bonds and separates the cation and anion. Water's polarity is the reason why it surrounds each ion and separates it from the oppositely charged

When are water molecules are polar?

The oxygen atom of a water molecule has a d- (delta negative) charge and the two hydrogens both have a d+ (delta positive) charge, a dipole exists. This allows for hydrogen bo

Is a water molecule polar and linear?

Its polar and bent. The two lone pairs of electrons push on the hydrogen bonds creating a bent shape. Btw this is common knowledge and could be found with a quick google searc

What is polarity in a water molecule?

The oxygen and hydrogen in water are bonded by a covalent bond. This means that the two lone lone electrons of hydrogen are shared with oxygen. Oxygen has a tendency to "hoard

Why is water a polar molecule but fluorine is not?

In a molecule of water, you have a bunch of unshared electrons on the oxygen side of the molecule (the negative end) and no electrons and two hydrogen nuclei on the hydrogen e
