Why does silver nitrate combine first with chloride ions in water and not with K2CrO4?
What really combines is silver ion. Silver chloride is 1/10 soluble than silver chromate in the cold, 1/3 in hot water. That means silver will incline to precipitate as AgCl preferentially. Moreover, if chromate will form it will convert to silver chloride
What is the formula for patassium dichromate?
The chemical formula of potassium dichromate is K2Cr2O7
What substance is a yellow solid at room temperature and 1atm?
K2CrO4
How 1 mg of K2CrO4 has thrice the number of ions than the number of formula unit when ionized in water?
1 mg of k2CrO4 has thrice the number ions than the number of formula units when ionized 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
Symbol for dichromate?
Potassium chromate is K2CrO4 Potassium dichromate is K2Cr2O7
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 K2CrO4 organic?
