Calculate the molar solubility of Ag Cros in water. Use 1.10 x 10-12 as the solubility product constant of Ag2CrO4. O 7.42 x 10-7M
O 1.05 x 10-6 M
O 6.50 x 10-5 M
O 1.03 x 10-4 M

answer

the ions in solute supperate from eachouthere

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).
