More Serious Skin Problems. The main feature distinguishing chronic hives from more serious skin disorders is whether the welts are filled with fluid. If the red bumps are itchy, inflamed, and filled with fluid, the condition is most likely hives. If theyâre hard and filled with other material besides fluid, and if after a skin test the lesions have a brownish color, thereâs most likely an underlying problem.
In the case of salty taste, taste-active ingredients are salts of sodium, potassium and lithium. The most common of these is, of course, table salt, or sodium chloride. When the salt dissolves into the saliva, it separates into positive and negative ions. Only the positive ions (sodium, potassium or lithium) have an impact on salty taste.
Sodium chloride is readily water-soluble, so if this crude salt were exposed to condensation or rain water, the sodium chloride could be dissolved and removed, and the salt could in effect lose its saltiness. Also, the salty flavour is detected by our sense of taste. If there were a physiological change in the functioning of our taste buds, salt consumed may no longer taste the same, but this would not be due to any inherent change in the salt itself. In summary, salt, i.e. sodium chloride, is a very stable material which retains its properties when stored dry.
