K2Cr2O7 + 7H2C2O4.2H2O + 6CO2 + 11H2O à 2K[Cr(H2O)2(C2O4)2].2H2O
The above mentioned reaction equation is correct except for the coefficient on the water product. I believe the coefficient of the water product is 13, not 11.
Yes, because chemical properties of sodium and potassium ions are nearly same.
Potassium chromate K2Cr(VI)O4 Indicates the oxidation state of the chromium component.
KCrO4 does not exist it is K2CrO4 and is called Potassium Chromate. Potassium dichromate is K2Cr2O7
Chromate
Beryllium Chromate = BeCrO4
Yes, because chemical properties of sodium and potassium ions are nearly same.
No, Potassium chromate is a compound
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
Potassium chromate K2Cr(VI)O4 Indicates the oxidation state of the chromium component.
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
The reaction between magnesium nitrate and potassium chromate is a chemical change. 2KOH(aq) + Mg(NO3)2(aq) --> 2KNO2(aq) + Mg(OH)2(s)
KCrO4 does not exist it is K2CrO4 and is called Potassium Chromate. Potassium dichromate is K2Cr2O7
K2CrO4 + BaSo4 ----------> BaCrO4 (Precipitate) + K2SO4 Potassium Barium Barium Potassium Chromate Sulphate Chromate Sulphate It Is A Double Displacement Reaction
Chromate
by the reaction of lead nitrate with potassium chromate or potassium dichromate
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+
I think Potassium chromate is not used in medicines. However, Potassium dichromate is used in making a homeopathic medicine called Kali Bichromicum
