-2
The valency of sulfate (SO4) is calculated by considering the individual valencies of the atoms that make up the ion. In sulfate, the sulfur atom has a valency of +6, and each oxygen atom has a valency of -2. Therefore, the overall valency of sulfate is -2, calculated as (+6) + 4(-2).
The formula of the sulphate ion is SO42-
Symbol for sodium cation is 'Na(+)' Its valency is '1'.
The valency of sulphite is 2-, meaning it has a charge of -2. The valency of sulfate is 2-, meaning it also has a charge of -2.
The valency of copper in copper sulfate (CuSO4) is +2. This means that copper has a charge of +2 in this compound and it forms ionic bonds with the sulfate ion.
The valency of a sulfate ion is -2, meaning it has a charge of -2 due to the presence of four oxygen atoms and a sulfur atom. This valency allows the sulfate ion to form compounds with metals and other ions through ionic bonding.
The valency of sulfate (SO4) is calculated by considering the individual valencies of the atoms that make up the ion. In sulfate, the sulfur atom has a valency of +6, and each oxygen atom has a valency of -2. Therefore, the overall valency of sulfate is -2, calculated as (+6) + 4(-2).
The valency of the chromate ion is 2-. This means that the chromate ion has a charge of -2.
The valency of sulfate is 2 because it contains a negatively charged sulfate ion (SO4) with a charge of -2. The sulfate ion forms ionic compounds by combining with positively charged ions, and to achieve a neutral overall charge in the compound, the valency of sulfate must be 2.
The valency of bromide ion (Br-) is -1.
The sulfate anion has a valency of 2-, i.e. it is SO4^2-
The formula of the sulphate ion is SO42-
The valency of the silicate ion is -4, meaning it has a charge of -4. This is because the silicate ion is made up of one silicon atom (which has a valency of +4) and four oxygen atoms (each with a valency of -2).
the valency of silicate ion is 4-
Symbol for sodium cation is 'Na(+)' Its valency is '1'.
The valency of hydrogen sulfate is -1. It has the chemical formula HSO4-.
Plumbate ion has a valency of -2. It is written as Pb4+ in ion exchange resins.
