Ask a question, if you are not sure about what to do or if you are confused about the content of the problem. Note: some reactions are given and some are not. Kb = 4. 4 x 10: ph = 1. 18. Electronegativities: cl = 2. 8; i = 2. 2; se = 2. 5; f = 4. 0; br = 2. 8; H3o (aq) + a (aq: ph = 6. 40, ph = 3. 20, ph = 5. 29, ph = 7. 00, ph = 6. 70, on average the ph of elmer"s glue is about 6. 7. Ka (c6h5cooh) = 6. 5 x 10-8: ph = 7. 81, ph = 2. 91, ph = 11. 09, ph = 3. 09, ph = 10. 91, (bonus) a titration of 50 ml of 0. 10 m hcn required 50 ml of 0. 10 m naoh.
