                      Did you know ants contain formic acid?





                   A species known as the yellow mad
             ant  has  been  eradicated  from  the

             Pacific. For about a decade, ants have
             threatened seabirds by swarming their
             nests  and  anything  on  the  ground.
             Ants  sprayed  formic  acid  on  birds,
             causing injuries and even death, Dinas

             Perikanan  dan  Margasatwa    officials
             said.

                  Ant acid/formic acid is the simplest

             formula HCOOH. The name formic acid                          Sumber: Glencoe, 2002
             comes  from  the  Latin  word  formica                   nb: silahkan klik gambar untuk

             outside.  Formic  acid  is  soluble  with  water.  The  reaction  of  ionization  of

             formic acid in water is as follows:





                  The writing of H3O+  ions in water can simply be written with H+(aq) So
             that the reaction equation becomes:






             In the above discourse, why is the formiate content in ants called acid?
