Valency = 2 -
The formula for a chromate ion is CrO4-2, and its charge is -2.
The charge is minus 2.
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 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 dioxonitrate (NO2-) is -1. Each oxygen atom in the dioxonitrate ion has a valency of -2, while the nitrogen atom has a valency of +3, resulting in an overall charge of -1 for the ion.
The color of chromate ion is yellow.
The formula for a chromate ion is CrO4-2, and its charge is -2.
The formula, including the charge, for a chromate ion is CrO4-1.
The chromate ion (CrO4^2-) is yellow in color.
The symbol for a chromate ion is CrO4^2-.
The valency of bromide ion (Br-) is -1.
The charge is minus 2.
Formula: CrO4-2
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'.
Chromate ion is a polyatomic anion with the formula CrO4^2-. It is a powerful oxidizing agent commonly used in chemical reactions, such as in the production of pigments and in corrosion protection coatings. Chromate compounds are also known for their yellow color.
