Question 6 Consider two 1 liter solutions: solution A contains a strong base at 0.1 M, solution B contains a weak base at 0.1 M with Kb 10-5. To both solutions, you add 0.05 mol of a strong acid. Select all statements that correctly describe the resulting solutions: = The pH of solution B is 9.0. The pH of solution A is 12.7. Solution A is still a strong base, solution B is a buffer. More acid needs to be added for both solutions to reach the equivalence point. Solution A is now a weak base, solution B is weakly acidic. ✔ Solution A has not reached the equivalence point, solution B is past the equivalence point. Both solutions are now buffers.
