If you added salt instead of sugar to a pitcher of lemonade, how would this change the properties of the lemonade?

If salt is added to lemonade instead of sugar, then the lifetime

of the lemonade is vastly increased. That is, it lasts a lot longer

than it normally would.

The effect has nothing to do with the intrinsic (internal) properties

of the lemonade, such as physical or chemical properties.

The effect is rather an external, mainly socio-cultural one.

With salt dissolved in it, in an amount roughly equal to the

otherwise typical amount of sugar, anyone at the party who tastes

the lemonade encounters the series of physiological reactions

described in medical terms as the "Trans-Mongolian bleah, yuk, feh,

waugch, hoo boy" syndrome. That particular individual stays as far

away from the pitcher as possible for the rest of the evening, and

may even communicate a vivid description of his experience to

others, whether explicitly or implicitly. A general sense of repulsion

thus propagates throughout the group, and the rate of change of

the quantity remaining in the pitcher decays to virtually zero, vastly

extending the life of that batch of the beverage.
