At a certain temperature* (probably not 25 °C), the solubility of silver sulfate, Ag2SO4, is 0.012 mol/L. Calculate its solubility product constant for this temperature. SIG. FIG. (required because number is small) Solubility product constants are very temperature sensitive. They are generally reported at 25°C. Not necessarily using this temperature allows me some flexibility. Answer: At a certain temperature, the solubility of potassium iodate, KIO3, is 36.1 g/L. Calculate its solubility product constant for this temperature. Answer: At a certain...

What did you need to help solve this? Solid calcium nitrate is slowly added to 175 mL of a 0.0514 M sodium sulfide solution. The concentration of calcium ion required to just initiate precipitation is M. When 22.0 mL of a 4.95x10-4 M copper(II) iodide solution is combined with 12.0 mL of a 4.68x10-4 M sodium carbonate solution does a precipitate form? (yes or no) For these conditions the Reaction Quotient, Q, is equal to
