Properties: colorless transparent crystal or powder. The crystal
structure have two kinds of forms, namely the alpha and beta type
(diamond) type (single inclined crystal shape). No smell, taste is
sour.
This material is harmful to the environment, water and
atmosphere of the pollution caused by organic acid, can be easily
in atmospheric chemistry, and the atmosphere in the physical change
form acid rain. So when PH value to 5 below in animal and plant
cause serious harm, fish breeding and development be severely
affected soil and water, river basin in the sediment can be
dissolved metal into the water poisoning fish. The acidification of
the water in the composition of the aquatic organisms structure
changes of algae and fungi, acid increased, while those with roots
plants, bacteria and vertebrates, reduce the decomposition of the
organic matter rate to decrease. Will lead to serious after the
acidification of the lakes, rivers, fish reduce or death in.
