If the saturated solution is cooled from 90 degree Celsius to 60 degree Celsius, how many grams of precipitate will be formed? The solubility-product constant for MgCO_{3} is 3.5*10^{-8} at 25 degrees Celsius. \;\cancel{\rm{g} \; \rm{H_2O}}}\)= \( {\text {28.83}}\)\({\rm{g} \; \rm{Hg(CN)_2}}\). Is the solubility of copper (II) hydroxide in 0.10 M NaOH greater than, less than or equal to its solubility in pure water? Explanation: You already know that potassium nitrate, KNO3, has a solubility of 155 g per 100 g of water at 75 degrees Celsius and 38.0 g at 25 degrees Celsius. What is the solubility of potassium hydroxide (KOH) in water? Place the water bath and test tube #1 on the stand (already set up), firmly attached. Appendix G is the answer.
