A buffer solution is prepared by adding 1.00 mole of lactic acid and 0.80 mole of sodium lactate to 1 kg of water. Assume that water is at unit activity and that the activity coefficient of each univalent ion is 0.65 throughout this problem. (a) Find the pH (in the activity sense) of this solution at 25°C. (b) Find the change in the pH of the solution resulting from the addition of 0.50 mole of sodium hydroxide to the quantity of solution containing 1 kg of water. (c) Find the change in pH resulting from the addition of 0.50 mole of sodium hydroxide to 1 kg of pure water at 25°C.\",\"src\":\"stemez-PhysicalChemistry\"}","display_format":"text","language":"","answer_status":"published","assets":[],"source_url":"https://huggingface.co/datasets/TIGER-Lab/MMLU-Pro","history":"initial import","indexing_mode":"index","subproblems":[],"grids":[]}
