The sugar substitute saccharin (C7H5NO3S) is a very weak acid (Ka = 2.1 × 10-12 - think carefully about the magnitude of this number). Calculate the pH in a solution that contains 3.48 g of saccharin per litre. You may not neglect the autohydrolysis of water in this problem. (note the answer should be 6.65)
The product contains a three carbon chain (from the alcohol) connected to a five carbon chain (from the acid) by an ester linkage. Review the structure of an ester. The sp3 intermediate contains three oxygen atoms, two from the acid and one from t..
