For those that are not neutral, write balanced equation for reactions causing the solution to be acidic or basic and give the equilibrium constant for that reaction. Example 6. ]The fundamental concept of this theory is that an acid (or Brnsted acid) is defined as being able to lose, or "donate" a proton (the hydrogen cation, or H+) while a base (or Brnsted base) is defined as a species with the ability to gain, or "accept," a proton. I hope that these hydrogens before carbons are just "accident" and not some misconception - edit accordingly. 1) The chemical reaction for the hydrolysis is: Example #5: Pyridine (C5H5N) is a weak base and reacts with HCl as follows: What is the pH of a 0.015 M solution of the pyridinium ion (C5H5NH+)?
