Because barium sulfate is opaque to X-rays, it is suspended in water and taken internally to make the gastrointestinal tract visible in an X-ray photograph. Although barium ion is quite toxic, barium sulfate’s Ksp of 1.1 x 10–10 gives it such low solubility that it can be safely consumed.
(a) What is the molar solubility of BaSO4?
(b) What is its solubility in grams per 100 g of water?
(i) Silver tarnishes in the presence of hydrogen sulfide (produced by rotten eggs) and oxygen because of the reaction below: 4Ag + 2H2S + O2 → 2Ag2S + 2H2O How many grams of Ag2S could be obtained from a mixture of 0.95 g Ag, 0.140 g H2S and 0.08 g O2 ?
(ii) At 20°C the solubility limit of silver(I)sulfate (Ag2SO4) is 0.800 g/100 mL. What is the molarity of such a solution?
(iii) What volume in mL of concentrated H2SO4 (18.0 M) must be used to prepare 400 mL of 3.0 M H2SO4 solution?
of the five salts listed below, which has the highest concentration of its cation in water? assume that all salt solutions are saturated and that the ions do not undergo any additional reactions in water. (a) lead(ii) chromate, ksp = 2.8 × 10–13 (b) cobalt(ii) hydroxide, ksp = 1.3 × 10–15 (c) cobalt(ii) sulfide, ksp = 5 × 10–22 (d) chromium(iii) hydroxide, ksp = 1.6 × 10–30 (e) silver sulfide, ksp = 6 × 10–51
