Five grams of barium hydroxide is dumped into a beaker of water at 25 degrees Celsius and allowed to dissolve and come to equilibrium. What is the final concentration of hydroxide? (Hint 1: 5 grams is way too much to actually dissolve, so the amount 5 grams will not actually be used. Hint 2: for every barium ion that forms, two hydroxide ions form: use algebra.)
