The partition coefficient of a base B (monoacidic) at a particular pH, in an octanol-water mixture is 1.45. Consider an experiment where 3.5 g of B are shaken with 100 mL of octanol and 50 mL of water.

Molar mass of B = 101.19 g mol-1


(i) Calculate the mass of B in the aqueous layer after shaking.

53.8 grams of a complex, diamminebis(oxalato)cobaltate(II), were dissolved in water and its ligand field splitting energy was measured as 55.0 kJ. What is the color of the complex?

How many grams of ammonia chloride must be added to 0.05kg of water to produce a solution that freezes at -5°C? The cryoscopic constant of water is 1.86°C kg mol-1. The molar mass of ammonium chloride is 53.5gmol-1

Calcium hydroxide and calcium sulfate are both used to prepare a saturated solution, S. Both solids are only sparingly soluble, and the pH of S is found to be 11.6. (i) Given that the Ksp for calcium hydroxide is 4.0 x 10-5 and the Ksp for calcium sulfate is 2.5 x 10-5 , determine the concentration of sulfate ions present in S.
