NH3,CuSO4,C2H5OH,CuCl2 Ion-dipole forces- CuCl2, CuSO4 Chapter 5 Solution Preparation Review What volume of 8.00 M sulfuric acid should be diluted to produce 0.500 L of 0.250 M solution? Name * Therefore, when preparing volume/volume percent solutions, it is always better to dissolve the solute in solvent and then add additional solvent to bring the total solution volume to the desired final value. The same dissolution behaviour, with the formation of negligible or minor amounts of solid tungstic acid was observed in the leaching of Swedish scheelite (71.4% WO 3) and upgraded Turkish scheelite (65.18% WO 3) concentrates.
