A chemist titrates 220.0 mL of a 0.8578 M pyridine (CH_N) solution with 0.6906 M HBr solution at 25 °C. Calculate the pH at equivalence. The pK, of pyridine is 8.77
Round your answer to 2 decimal places.
Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of HBr solution added.

The  grandmother cell  is a hypothetical  neuronthat represents a complex but specific concept or object.[1]  it activates when a person "sees, hears, or otherwise sensibly discriminates"[2]  a specific entity, such as his or her grandmother. the term was in use at least as early as 1966 amongst staff and students in the department of experimental psychology, university of cambridge, england. a similar concept, that of the  gnostic neuron, was proposed two years later
