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 is the precipitate color formed from barium chloride and potassium chromate?
The precipitate formed from the reaction between barium chloride and potassium chromate is a yellow solid known as barium chromate.
What is the name of this formula k2CrO4?
KCrO4 does not exist it is K2CrO4 and is called Potassium Chromate. Potassium dichromate is K2Cr2O7
When potassium chromate dissolves in water what ions are produced?
When potassium chromate dissolves in water, it produces potassium ions (K⁺) and chromate ions (CrO₄²⁻).
How can we prepare potassium chromate?
To prepare potassium chromate, start by dissolving potassium dichromate in water and then adding potassium hydroxide to adjust the pH. The solution is then heated to evaporate water, leaving behind potassium chromate crystals. Purify the crystals by recrystallization to obtain pure potassium chromate.

Is potassium chromate a cation?
No, Potassium chromate is a compound
What is the name of this formula k2CrO4?
KCrO4 does not exist it is K2CrO4 and is called Potassium Chromate. Potassium dichromate is K2Cr2O7

When potassium chromate dissolves in water, it produces potassium ions (K⁺) and chromate ions (CrO₄²⁻).
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.

The solution is then heated to evaporate water, leaving behind potassium chromate crystals. Purify the crystals by recrystallization to obtain pure potassium chromate.
Is there any way to make lead chromate?
by the reaction of lead nitrate with potassium chromate or potassium dichromate
What color is k2cro4?
Potassium chromate (K2CrO4) is a yellow colored compound.
What the name of K2CrO4?
This is an impossible reaction. However if you turn it around and do AgNO3 plus K2CrO4 then it is equal to Ag2CrO4 plus 2KNO3.
What happens when potassium chromate is treated with barium nitrate?
When potassium chromate is treated with barium nitrate, a double displacement reaction occurs. Barium chromate and potassium nitrate are formed as products. A yellow precipitate of barium chromate is observed in the reaction mixture.
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.
