KCrO4 does not exist it is K2CrO4 and is called Potassium Chromate. Potassium dichromate is K2Cr2O7
potassium chromate
Potassium chromate K2Cr(VI)O4 Indicates the oxidation state of the chromium component.
Potassium chromate is K2CrO4 Potassium dichromate is K2Cr2O7
BaCl2+K2CrO4--------->BaCrO4+2KCl BaCrO4 is a yellow precipitate.
BaCrO4
Chromate
Formula: K2CrO4
Formula: K2CrO4
Formula: K2CrO4
Formula: K2CrO4
1 mg of k2CrO4 has thrice the number ions than the number of formula units when ionized in water ?
Potassium chromate K2Cr(VI)O4 Indicates the oxidation state of the chromium component.
The chemical formula of dipotassium chromate is K2CrO4.The explanation of the name is:- this compound is a salt- the cation is potassium (and here are two atoms of K)- the anion is chromate- consequently the correct derived name will be dipotassium chromate
K2CrO4 Molarity (concentration) = moles of solute/Liters of solution (100 ml = 0.100 Liters ) Find moles K2CrO4 first. 3.50 grams = (1 mole K2CrO4/194.2 grams) = 0.01802 moles K2CrO4 ----------------------------------------------next Molarity = 0.01802 moles K2CrO4/0.100 Liters = 0.180 M K2CrO4 -------------------------

This is a mixture of 2K+ and Cr2O72- ions in strong sulfuric acid.2CrO4- + 2H+ ----> Cr2O72- + H2Ochromate-yellow -> dichromate-orangeNote:Potassium ions do NOT react, they are tribune-ions
Reaction of Potassium hydroxide or any potassium salt of a weak acid with chromic acid produces Potassium chromate. KOH + H2CrO4 ----> K2CrO4 + H2O K+ + H2CrO4 ----> K2CrO4 + H+
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.
