Well, the whole thing is very complicated. The asorbic acid in sour, compliments the falic acid in other sour foods. It may seem more sour to you if you taste sour on sour, but it is just your taste buds reacting to two different chemicals. Both chemicals combined make it very easy to be tasted, and sometimes disliked. When you taste sour on salty it's harder to taste. One ingredient in salt, called cottonseed extract, mainly counteracts most asorbic and falic acids. So, in most salty foods it's harder to taste sour things.
