Saltiness

Any flavor or gustatory perception that could be loosely described as something like tasting the ocean is called a salty sensation. We use words like briny, fresh, metallic, clean, acrid, pure, fishy, drinkable, alkaline, saline, antacid, palatable, medicinal, pickled etc. to describe salty flavors. These sensations are objectified as a class of chemical compounds generically called salts. They are all modeled by molecules composed from at least two atoms.
A naturally occurring crystal of //sodium chloride//, also known as table salt, from a potash mine in Saskatchewan, Canada.

We make binary descriptions of these flavors by comparing them with reference sensations. Results are reported using one of the following algebraic statements. If a sensation is completely different from tasting the ocean, then say it is not comparable to a salty taste sensation and write

$\delta_{\sf{I}}=0$

If a sensation is strongly like tasting the ocean, then call it a brackish taste and express this as

$\delta_{\sf{I}}=+1$

If the taste is just weakly like tasting like the ocean, then say it is potable and report

$\delta_{\sf{I}}=-1$

The number $\delta_{\sf{I}}$ is called the saltiness. We use a picture of a big ocean wave as an icon for salty taste sensations. You can always click on icons to come back to a page like this for easy reference.
