Is nitrate a polar or non-polar molecule? I understand that it has a trigonal planer shape (and therefore it has symmetry) but should we also consider the double bond (do multiple bonds destroy symmetry)? I assume it would be polar because it is SOLUBLE in WATER, however, after viewing many links online, many people say it is non-polar.

Is nitrate a polar or non-polar molecule?

You say nitrate, as in the ion NO₃^-? Polar and non-polar apply only to molecular compounds
