Yes, it is both acidic (donating H+, conjugate base PO43-) and basic (accepting conjugate acid H2PO4-)
[ 'amphi' means 'both' ]
Fe+3 SO4-2
The species in question is the sulfate ion, which has a 2- charge. It is thus properly written as SO42-
The chemical formula of ammonium alum is (NH4)Al(SO4)2·12H2O.
Sulphuric Acid No - H2SO4 is sulphuric acid. SO4 on its own like this is sulphur tetroxide SO4 2- would be the sulphate ion.
AL = aluminum K= potassium S= sulfate
SO4 is not a molecule. (SO4)2- is the sulfate ion.
It is SO4 -2 named as sulphate ion.
Fe+3 SO4-2
Pb(2+) is the cation and (SO4)2- is the anion.
The species in question is the sulfate ion, which has a 2- charge. It is thus properly written as SO42-
Sulphate SO4 2-
The oxydation state for S in (SO4)2- is 6.
It is not amphotetic.It a very stron acid.
SO4^2- has a net negative 2 charge.each O = 2-S = 6+
The chemical formula of ammonium alum is (NH4)Al(SO4)2·12H2O.
Sulphuric Acid No - H2SO4 is sulphuric acid. SO4 on its own like this is sulphur tetroxide SO4 2- would be the sulphate ion.
The chemical formula of the ion sulfate is (SO4)2-.
