i think its 2
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 sodium in sodium sulfate is +1, while the valency of sulfate is -2. Therefore, the valency of sodium sulfate as a whole is +2.
The valency of magnesium in magnesium sulfate is +2, as magnesium typically forms ions with a charge of +2. Sulfate (SO4) has a valency of -2 because it usually gains two electrons to achieve a stable octet.
The valency of hydrogen sulfate is -1. It has the chemical formula HSO4-.
The valency of sulfur in ammonium sulfate is 6. This is because each sulfate ion (SO4^2-) contains one sulfur atom with a valency of 6 due to its ability to form 6 covalent bonds by accepting two electrons from each of the four oxygen atoms.
The sulfate anion has a valency of 2-, i.e. it is SO4^2-
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 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 sodium in sodium sulfate is +1, while the valency of sulfate is -2. Therefore, the valency of sodium sulfate as a whole is +2.
Copper(II) sulphate is written like this because here II denotes the oxidation state of copper or in simple language, it denotes its valency.Copper sometimes shows +1 valency and sometimes +2.So to specify, its valency in a compound, the valency is written in brackets.
Valency of k=1+ valency so4=2- after crisscrossing the valencies, we get- chemical formula- k2so4
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 magnesium in magnesium sulfate is +2, as magnesium typically forms ions with a charge of +2. Sulfate (SO4) has a valency of -2 because it usually gains two electrons to achieve a stable octet.
The valency of hydrogen sulfate is -1. It has the chemical formula HSO4-.
The valency of sulfur in ammonium sulfate is 6. This is because each sulfate ion (SO4^2-) contains one sulfur atom with a valency of 6 due to its ability to form 6 covalent bonds by accepting two electrons from each of the four oxygen atoms.
Copper II sulphate has variable valency properties, which translates to variable charges.
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.
