Formula: K2CrO4
No, Potassium chromate is a compound
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⁻).
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.
by the reaction of lead nitrate with potassium chromate or potassium dichromate
This is an impossible reaction. However if you turn it around and do AgNO3 plus K2CrO4 then it is equal to Ag2CrO4 plus 2KNO3.
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.
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.
When potassium chromate reacts with barium sulfate, a precipitation reaction occurs. Barium chromate is formed as a yellow precipitate, while potassium sulfate remains in solution. This reaction can be used to detect the presence of sulfate ions in a solution.
The chemical symbol for chromate is CrO4^2-.
The symbol for a chromate ion is CrO4^2-.
Barium Chromate = BaCrO4
