What is the solubility of la(io) in water_ (ksp of la(io) is 7.5 10)

Aug 14, 2020 · Estimate the solubility of La(IO 3) 3 and calculate the concentration of iodate in equilibrium with solid lanthanum iodate, for which K s = 6.2 × 10 –12. Solution. The equation for the dissolution is \[\ce{La(IO_3)_3 <=> La^{3+ } + 3 IO3^{–}} onumber\] If the solubility is S, then the equilibrium concentrations of the ions will be Chemistry 12 Tutorial 10—Solutions Chemistry 12—Tutorial 10 Solutions Page 3 of 5 pages 3 Ksp 4 4.9 x 10-17 4 3 2.6K x 10-9 3. a) Calculate the molar solubility (solubility in moles/Litre) of Fe(OH)2 in water.-s +s +2s (where "s" is the molar solubility)It can be demonstrated that the Ksp value is sensitive to ionic strength and accurate work requires the determination of the Ksp at "zero" ionic strength. This is sometimes known as the thermodynamic equilibrium constant, Kth: Kth = a Ca 2+)(a IO 3. In this expression the ion concentrations are expressed as their activities. Estimate the solubility of La(IO 3) 3 and calculate the concentration of iodate in equilibrium with solid lanthanum iodate, for which K s = 6.2 × 10 -12. Solution. The equation for the dissolution is \[\ce{La(IO_3)_3 <=> La^{3+ } + 3 IO3^{-}} \nonumber\] If the solubility is S, then the equilibrium concentrations of the ions will be

Also, photolysis of acetone in water, based on a rate constant for the reaction of acetone with hydroxyl radicals in water at pH 7 of 5.8-7.7 × 10 7 litres/mol-sec and a concentration of hydroxyl radicals in eutrophic waters of 3 × 10-17 M (Mill & Mabey, 1985), will not be significant. Compare prices and find the best deal for the Oasi Rupestre in Montescaglioso (Basilicata) on KAYAK. Rates from $68. The iodate ion concentration of a saturated solution of La(IO 3) 3 was found to be 3.1 × 10 –3 mol/L. Find the K sp. Find the concentration of iodate ions in a saturated solution of Cu(IO 3) 2 (K sp = 7.4 × 10 –8). Calculate the molar solubility of AgBr in 0.035 M NaBr (K sp = 5 × 10 –13).


DRINKING WATER: p-Diisopropylbenzene was qualitatively detected in drinking water samples collected from treatment facilities in Philadelphia, PA (Feb 10, 1976), Ottumwa, IO (Sep 10, 1976), and Seattle, WA (Nov 5, 1976)(1). NaCl has a solubility of 35.7 g/100 mL. What is the molar solubility and Ksp? (Ans: 6.10 M, 37.2) 2. CaCl2 has a solubility of 74.5 g/100 mL. What is the molar solubility and Ksp? (Ans: 6.71 M, 1.21 X 103) 4 5 Solubility Ksp and Solubility 3. BaF2 has a molar solubility of 0.0068 M. How many grams will dissolve in 600.0 mL? (Ans: 0.72 grams) 4.
