Tried to, but it made no difference.
BTW, I don't think it's possible to know what sodium tastes like. AFAIK,
as soon as you put a chunk of sodium in your mouth, it reacts with the
water in your saliva, producing Na+ and OH-, as well as some very
unpleasant other effects. So Na+ and OH- is what you will actually
taste. If you are foolish ennough to try the experiment. :-)
Similar observations hold about tasting chlorine.
