Unformatted text preview: ation of gypsum, CaSO4(s), is 104.85. If a solution containing 102.0 M SO42 is in equilibrium with gypsum, what is pCa2+?
Ca2+ + SO42 ↔ CaSO4(s) The dissolved oxygen concentration in a pond increases from 2 to 16 mg/L during a sunny day due to algal photosynthesis. If the water temperature is 20oC, will O2 entering the pond from the atmosphere or leave the pond and transfer into the atmosphere during the day? K for the reaction transferring O2 from solution to the atmosphere is 790. THE DISSOCIATON OF WATER • Water can dissociate into H+ and...
