words matched: anions
The additional negative ions test tube reactions for nitrate(III), nitrate(V), sulfate(IV), phosphate and carboxylates (methanoate and ethanoate).
words matched: anions
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..
