K2CrO4 is insoluble in water because the forces holding the ions together in the solid state are stronger than the forces between the ions and water molecules. The lattice energy of K2CrO4 is high due to the strong ionic bonds between potassium and chromate ions, which makes it energetically unfavorable for the compound to dissociate in water.
What else can I help you with?
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 -------------------------
Is Ag2CrO4 soluble or insoluble in water?
Ag2CrO4 is insoluble in water.
Which substance is insoluble in tap water?
oils are insoluble in water
If a compound is insoluble in water why is it also insoluble in blood?
If a compound is insoluble in water, it will likely be insoluble in blood as well because blood is primarily water-based. The compound's chemical properties that make it insoluble in water will also prevent it from dissolving in the aqueous environment of blood.
Which element occur in compounds that are insoluble in water?
Many organic compounds are insoluble in water. They have carbon and hydrogen as elements.
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 is the whit precitate in bacl2 plus k2cro4?
The white precipitate formed in the reaction between BaCl2 and K2CrO4 is BaCrO4 (barium chromate). This precipitate forms because Ba2+ ions from BaCl2 react with CrO4^2- ions from K2CrO4 to produce an insoluble compound that falls out of solution.
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.

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 formula for K2CrO4?
The chemical formula for potassium chromate is K2CrO4.
Why is something insoluble in water?
Oils are insoluble in water because they are bases.
