SO4 -----> 2- (negative 2)
Sulfate is a negative ion composed of the nonmetals sulfur and oxygen bus is itself not a metal or a nonmetal. The sulfate ion does not exist as a substance on its own. Its charge must be balanced by a positive ion the identity of that ion is variable.
the chemical formula of zinc sulphate is ZnSO4.
In oxygen containing anions that also include a less electronegative element, oxygen is taken to have an oxidation number of -2. A sulfate ion has a charge of -2. The four oxygen atoms of a sulfate ion have a total charge of 4 X -2 or -8; therefore, the oxygen atom must have an oxidation number of +6 to yield the correct value for the charge of the sulfate ions.
The potassium ion is K+ and the sulfate ion is SO42-
Sulfate is the chemical name of an ion that is not a compound, which must have a neutral electrical charge; instead, each sulfate ion has a charge of -2. As a result, "sulfate" can not exist in isolation from all other substances, but rather must be paired with positively charged partners such as cations, of which sodium is an example. It should be noted that sodium lauryl sulfate does not even contain sulfate ions as such, but rather lauryl sulfate ions, which contain carbon and hydrogen as well as sulfur and oxygen.
Sulfate ion is SO42-, so the charge is -2.
The species in question is the sulfate ion, which has a 2- charge. It is thus properly written as SO42-
The sulfate ion is SO42-. Elements in group 16 form anions with a charge of 2-, for example oxygen forms the oxide, O2- anion.
Sulfate is a negative ion with the formula SO42- in order to balance the charge there needs to be a positive ion, which usually is a metal ion, but not always. However, the sulfate ion itself is not a metal nor does it contain a metal.
What is the charge on the iron ion in FE2(SO4)3
Yes. The charge on Na (sodium) ions is 1+ and the charge on a SO4 (sulfate) ion is 2-. So to balance out the charges 2 sodium ions are needed for every sulfate ion.
SO4 2-
Sulfate is a negative ion composed of the nonmetals sulfur and oxygen bus is itself not a metal or a nonmetal. The sulfate ion does not exist as a substance on its own. Its charge must be balanced by a positive ion the identity of that ion is variable.
SO4-2The sulfate ion is a polyatomic ion made up of one sulfur atom and four oxygen atoms, that exists only if it can gain 2 electrons (from some metal cation or cations). It has a charge of -2. Note that this is the sulfate ion and not the sulfiteion.
the chemical formula of zinc sulphate is ZnSO4.
In oxygen containing anions that also include a less electronegative element, oxygen is taken to have an oxidation number of -2. A sulfate ion has a charge of -2. The four oxygen atoms of a sulfate ion have a total charge of 4 X -2 or -8; therefore, the oxygen atom must have an oxidation number of +6 to yield the correct value for the charge of the sulfate ions.
Potassium Sulfate, as it suggests, is made up of potassium and a sulfate ion. Potassium is an element shown as K on the periodic table. However, sulfate is a polyatomic ion (basically two or more atoms put together that have a charge). The formula for sulfate is SO4 with a charge of 2-. Potassium, on the other hand, has a charge of +1. Therefore, when you put the two together it would give you potassium sulfate, aka K2SO4.
