Why is a salt polar?

Not really, while salt (NaCl) does dissolve in polar substances, it does so by dissociating. Most polar substances remain intact molecules when they dissolve. To some extent, ionic compounds like salt could be considered so polar that they break apart in polar solvents.

Salt does not form molecules but ions. Sodium chloride is an ionic compound.

Ion for sodium is Na+ while ion for chlorine(chloride) is Cl-.

Like this :

Na----Cl

This diagram above shows it is a non-polar molecule.

The electropositivity of sodium balances with the electronegativity of chlorine.

A salt consists of a positive ion(s) bonded to a negative ion(s), and that contrast of charges makes it behave like something which is polar. This is why water, which is also very polar (but not ionic) will dissolve many types of ionic compounds.

Yes, it's very polar due to hydrogen bonding.

They are almost all ionic, not polar.

Though I doubt somewhat it be for e.g. CsI, cesium iodide, because it is so, so, so big! as compared to LiF, lithium fluoride

saltwater is not a substance, it is a mixture. if you take out the salt, then water is polar

Salt is not a bond, it is a type of compound. It has an ionic bond.

It's not polar or nonpolar, but ionic.
