Document Summary

For weak acids alone in water: pz= -logz. [h+][ho-] = 1. 00 x 10-14 ph + poh = 14. Kakb= 1. 00 x 10-14 for conjugate acid/base pair. 1. 00 l of 1. 00m ch3cooh (acetic acid, ka = 1. 8 x 10-5). If 0. 050 moles of hcl is added to this buffer solution, the ph of the solution will drop slightly. 2: 2. 51, 3. 89, 4. 49, 10. 11, consider a solution containing 0. 100 m naf and 0. 126 m hf. Znco3 can dissolve in 1. 0 l of water: 4. 69 x 10-4 g/l, 3. 74 x 10-6 g/l, 6. 39 x 10-2 g/l, 5. 43 x 10-4 g/l, none of the above, the solubility of mn(oh)2 is 2. 2 x 10-5 mol/l. What is the ksp of mn(oh)2: 1. 1 x 10-14, 4. 3 x 10-14, 2. 1 x 10-14, 4. 8 x 10-10, none of the above. 5: consider the following table of ksp values.
