crystal of copper sulfate CusO, SH,0 falls through a large tank of pure water at 20°C. Estimate the rate at which the crystal dissolves by calculating the flux of Cuso, from the crystal surface to the bulk solution. Repeat by calculating the flux of water. Data and assumptions: Molecular diffusion occurs through a film of water uniformly 0.0305 mm thick, surrounding the crystal. At the inner side of the film, adjacent to the crystal surface, the concentration of copper sulfate is its solubility value, 0.0229 mole fraction Cuso, (solution density - 1193 kg/m'). The outer surface of the film is pure water. The diffusivity of CuSO, is 7.29 x 10-10 m/s.

Question
A crystal of copper sulfate CusO, SH,0 falls through a large tank of pure water at 20°C. Estimate the rate at which the crystal dissolves by calculating the flux of Cuso, from the crystal surface to the bulk solution. Repeat by calculating the flux of water. Data and assumptions: Molecular diffusion occurs through a film of water uniformly 0.0305 mm thick, surrounding the crystal. At the inner side of the film, adjacent to the crystal surface, the concentration of copper sulfate is its solubility value, 0.0229 mole fraction Cuso, (solution density - 1193 kg/m'). The outer surface of the film is pure water. The diffusivity of CuSO, is 7.29 x 10-10 m/s.
