The structure for potassium trioxalato chromate (III) can be represented as K3[Cr(C2O4)3]. This compound consists of a potassium cation (K+) and a chromate (III) anion featuring three oxalate ligands bound to a central chromium ion.
Potassium chromate shows a yellow color because of its chemical structure. The color arises from the absorption of certain wavelengths of light by the compound, leading to the reflection of yellow light. This selective absorption is due to the arrangement of atoms and electrons within the chromate ion.
Sodium in one, but so are potassium and calcium.

Conversion is increased when the pH increase.
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.
When potassium and iodine react, they form potassium iodide. The ions involved are K+ (potassium ion) and I- (iodide ion).
The formula for potassium chromate is: K2CrO4. The formula provides the following information: there are two potassiums, 1 chromium, and 4 oxygens. It can also be inferred that the charge on the chromate polyatomic group is -2 to balance out the two +1 potassium cations.
you mean a base or an acid? K2CrO4 is a base
The color of chromate ion is yellow.
The valency of the chromate ion is 2-. This means that the chromate ion has a charge of -2.
The correct order from smallest to largest ionic radius is chloride ion < sulfide ion < potassium ion < calcium ion.
The formula for a chromate ion is CrO4-2, and its charge is -2.
Yes, sodium chromate can be used as a substitute for potassium chromate in certain applications. Both compounds are sources of the chromate ion, but there may be differences in solubility and reactivity that could affect their suitability for specific reactions or processes. It is important to consider any potential differences in properties when substituting one for the other.
The formula of the dichromate ion is Cr2O72-
The formula, including the charge, for a chromate ion is CrO4-1.
The chromate ion (CrO4^2-) is yellow in color.
