What is the name of this formula k2CrO4?
KCrO4 does not exist it is K2CrO4 and is called Potassium Chromate. Potassium dichromate is K2Cr2O7
What is the dissociation equation for k2CrO4?
The dissociation equation for potassium chromate (K2CrO4) in water is: K2CrO4(s) -> 2K+(aq) + CrO4^2-(aq).
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.
How do you make 0.25N K2CrO4 solution?
To make a 0.25N K2CrO4 solution, you need to first calculate the molecular weight of K2CrO4 (potassium chromate). Then, determine the grams of K2CrO4 needed to make the desired volume of solution at a concentration of 0.25N. Dissolve this amount of K2CrO4 in the required volume of solvent, usually water, to make the final solution.
What color is k2cro4?
Potassium chromate (K2CrO4) is a yellow colored compound.
What is the name of this formula k2CrO4?

Potassium chromate formula?
Formula: K2CrO4
What is the symbol for potassium chromate?
Formula: K2CrO4
How do you write potassium chromate?
Formula: K2CrO4
What is the ion for K2CrO4?
The ion for K2CrO4 is the chromate ion, which has a chemical formula of CrO4^2-.
What is formula for potassium chromate?
The chemical formula for potassium chromate is K2CrO4. It consists of two potassium (K) atoms, one chromium (Cr) atom, and four oxygen (O) atoms.
How 1 mg of K2CrO4 has thrice the number of ions than the number of formula unit when ionized in water?
When 1 mg of K2CrO4 is dissolved in water, it will form 3 ions: 2 potassium ions (K+) and 1 chromate ion (CrO4^2-). This is because each formula unit of K2CrO4 contains 1 potassium ion and 1 chromate ion, resulting in a total of 3 ions when dissociated in water.
What is the chemical formula of potassium chromate?
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

How do you find the concentration of 3.50g of potassium chromate in 100 ml water?
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 -------------------------
