What is the structure for potassium trioxalato chromate 3?
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.
Why potassium chromate shows yellow color?
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.
What is an example of an ion of biological importance?
Sodium in one, but so are potassium and calcium.
Which ion in periodic table used in the body?
sodium potassium calcium iron
How do you convert dichromate ion into chromate ion?
Conversion is increased when the pH increase.
Which element is responsible for the yellow color of potassium chromate?
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.
What ions form when Potassium and Iodine react and what are their symbols?
When potassium and iodine react, they form potassium iodide. The ions involved are K+ (potassium ion) and I- (iodide ion).
What information is provided by the formula for potassium chromate?
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.
Is potassium chromate an acid or base?
you mean a base or an acid? K2CrO4 is a base
What is colour of chromate ion?
The color of chromate ion is yellow.
What is the valency of chromate ion?
The valency of the chromate ion is 2-. This means that the chromate ion has a charge of -2.
Arrange the following in order increasing ionic radius potassium ion sulfide ion chloride ion calcium ion?
The correct order from smallest to largest ionic radius is chloride ion < sulfide ion < potassium ion < calcium ion.
What is the symbol and charge for the ion chromate?
The formula for a chromate ion is CrO4-2, and its charge is -2.
Could sodium chromate be used instead of potassium chromate?
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.
