- Some barium chloride is added to a solution that contains both K2SO4 (0.050 M) and Na3PO4 (0.020 M). (a) Which begins to precipitate first: the barium sulfate or the barium phosphate? (b) The concentration of the first anion species to precipitate, either the sulfate or phosphate, decreases as the precipitate forms. What is the concentration of the first species when the second begins to precipitate?arrow_forwardSolubility is an equilibrium position, whereas Ksp is an equilibrium constant. Explain the difference.arrow_forwardThe Solubility Product Constant for silver hydroxide is 2.0 × 10-8. The molar solubility of silver hydroxide in a water solution is M.arrow_forward

What is the molar solubility of silver chloride in a 6.5 x 10−3 M AgNO3 aqueous solution at 298 K?arrow_forwardThe solubility of silver chromate (Ag2CrO4) in 500 mL of water at 25°C is 0.0129 g. Calculate its solubility product constant.arrow_forwardThe Ksp of calcium hydroxide, Ca(OH)2, is 1.3 × 10–6. Calculate the molar solubility of calcium hydroxide.arrow_forward
- = 1.6 x 10-10 Given the reactions below, calculate the molar solubility of AgCl (s) in 0.566 M NH3 (aq) at 25 degrees C. AgCl (s) →> Ag+ (aq) + Cl¯ (aq) K sp Ag+ (aq) + 2 NH3 (aq) →> Ag (NH3) + (aq) K = 1.7 x 107 f 2 Report your answer rounded to two significant figures and do NOT include units. Use "e" for scientific notation.
