Using your knowledge of the molecular basis for acid strength, explain the following observations: i) HClO4 is a stronger oxyacid than H2SeO4 ii) Nitrite (NO2-) is a stronger base than sulphite (SO32-)

Calcium sulfate is found in plaster. a) At 25 °C, Ksp for CaSO4 is 2.4 × 10-5. Determine the molar solubility in water and in 0.15 M CaCl2. b) Na2SO4 is added gradually to 100 cm3 of a solution that contains 0.15 M Ca2+ and 0.15 M Sr2+ ions (at 25 °C). De...
