A mixture of 100 mmol of Ca(OH)2 and 2 g of sodium sulphate was dissolved in water and the volume was made up to 100 mL. The mass of calcium sulphate formed and the cocentration of OH- in resulting solution, respectively, are: (Molar mass of Ca(OH)2, Na2SO4 and CaSO4 are 74, 143 and 136 g mol-1, respectively; Ksp of Ca(OH)2, is \(5.5 \times 10^{-6}\))
- 1.9 g, 0.14 mol L-1
- 13.6 g, 0.14 mol L-1
- 1.9 g, 0.28 mol L-1
- 13.6 g, 0.28 mol L-1
Answer
(A) 1.9 g, 0.14 mol L -1
