Lymph nodes are very small clusters of immune cells that function as part of the bodyâs immune system. There are more than 600 lymph nodes throughout the body, but the ones most frequently enlarged or swollen are the lymph nodes in the neck, under the chin, in the armpits, and in the groin.here are more than 600 lymph nodes throughout the body, but the ones most frequently enlarged or swollen are the lymph nodes in the neck, under the chin, in the armpits, and in the groin.
Uses of sulfuric acid. By far the largest amount of sulfuric acid is used to make phosphoric acid, used, in turn, to make the phosphate fertilizers, calcium dihydrogenphosphate and the ammonium phosphates. It is also used to make ammonium sulfate, which is a particularly important fertilizer in sulfur-deficient.
Hypochlorous acid is a weak acid that can only exist in solution, because it is highly unstable when isolated in a pure form. There are a number of uses for this chemical, most of which take advantage of its strong oxidating properties, which allow it to be used as a bleach and disinfectant, among many other things.o the other comments, obviously toxicity is often related to concentration. Very dilute hypochlorous acid is not particularly dangerous to people. From what I've read, nor is a 'slightly' acidified bleach solution (as the article seems to acknowledge with it's pH note!).
