Below are some potentially useful conversionfactors.1 lb1 gallon1 quart===453.6 g4 quartts0.946 L-33The precipitation of aluminum hydroxide, Al(OH)3 (Ksp = 1.3 × 10−³³), is commonly used to purify potable water. Itforms a spongy precipitate that settles slowly, carrying even very small suspended particles down with it, thereby removing allfinely divided matter and most microbes.Part AThe Ksp can be used to find the minimum concentration of hydroxide ions required to start the precipitation of Al(OH)3given a concentration of aluminum ions, and thus determine the pH above which this precipitation occurs.

North of Kingston you discover a hidden mountain and name it Mt. Kevinmanjaro, which weighs 1x1012 kg and is made entirely of CaCO3(s) (MW = 100 g/mol, Ksp = 3.3×10–9). Each year the mountain received approximately 1×106 L of rainfall, which flow from the mountain completely saturated with Ca2+(aq). How many years will it take to entirely dissolve Mt. Kevinmanjaro?
A fictional compound AX₂ has a molar mass of 235.76 g/mol and a Ksp of 3.8742e-10. It dissociates in water based on the equation: AX2(s) ⇒ A²+, (aq) + 2X (aq) Based on this information, label the statements below as true or false. If more solid AX₂ is added to the system then [A²+] will increase. If more soluble A(NO3)2 is added to the system then [X] will increase. ✓ If the solution is heated and the solubility increases, then the heat of solution for AX₂ is endothermic. ✓ The mass solubility of AX₂ is greater than 2.17E-2 g/100mL H₂O. ✓ If soluble Nax is added to the system then [A²+] will decrease. The molar solubility of AX₂ is greater than 9.18E-4 mol/L. If more solid AX₂ is added to the system then [X] will decrease.
