Yellow
The color of chromate ion is yellow.
The yellow color of potassium chromate is due to the presence of the chromate ion (CrO4^2-). This ion absorbs light in the blue region of the spectrum, leading to the perception of a yellow color.
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.
The formula, including the charge, for a chromate ion is CrO4-1.
The symbol for a chromate ion is CrO4^2-.

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.
The valency of the chromate ion is 2-. This means that the chromate ion has a charge of -2.
The chromate ion (CrO4-2) has yellow colour so all the chromate compounds including silver chromate is yellow in colour.
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 symbol for a chromate ion is CrO4^2-.
The charge is minus 2.
Formula: CrO4-2
Yello. The color comes from the chromate ion which is yellow. The ion is colored as it contains a transition metal atom and has readily excitable electrons.
The chromate ion has a charge of 2-. Its symbol is CrO42-.
