Practice problems for chapter 8 chem 1a. A solution contains 0. 36 m ha (ka = 2. 0 10-7) and 0. 24 m naa. Calculate the ph after 0. 04 mol of naoh is added to 1. 00 l of this solution. Calculate the ph of a solution that contains 3. 25 m hcn (ka = 6. 2 10-10), 1. 00 m naoh and 1. 50 m nacn. 9. 25 b) 8. 86 c) 8. 28 d) 7. 46 e) none of these. 6. 76 b) 6. 52 c) 6. 64 d) 6. 40 e) 6. 70. How many moles of hcl need to be added to 150. 0 ml of 0. 50 m naz to have a solution with a ph of 6. 50? (ka of hz is 2. 3 10-5. ) Calculate the ph of a solution made by mixing 33. 0 ml of 0. 340 m naa (ka for ha = 1. 0 10-8) with 26. 4 ml of 0. 100 m hcl. Consider a solution of 2. 0 m hcn and 1. 0 m nacn (ka for hcn = 6. 2 10 10).
