Because sulfur is +6 (6 valence electrons) but there are 4 oxygens at -2 bound to it so its net charge is +6 - 4 x -2 = -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 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.
