Risk assessment guidance for ammonia solution (ammonium hydroxide)
words matched: NH3(aq)
Testing for positive ions: reactions with hydroxides and ammonia. This microscale practical is carried out on a worksheet that is laminated or placed in a plastic wallet. The method minimises the use ..

The common negative ions, carbonate (CO32-),
sulfate(VI) (SO42-) and the halides (Cl–, Br–
and I–) can be simply tested for in test tube reactions. The method
described here uses a more dilute ammo..
