The Ksp can be used to find the concentration of hydroxide ions, and thus determine the pH given a concentration of of aluminum. At what pH will precipitation of Al(OH)3 begin if 6.70 lb of aluminum sulfate, Al2(SO4)3, is added to 2050 gallons of water (with a negligible change in volume)?

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
