Acid-Base Equilibria and Buffer Solutions

The video tutorial covers acid-base equilibrium, explaining how strong and weak acids and bases react with water. It introduces the concept of the acid ionization constant (Ka) and its relationship with pH, detailing how to calculate Ka and the degree of ionization. The tutorial also discusses buffer solutions, their role in maintaining pH stability, and the use of the Henderson-Hasselbalch equation to prepare buffer solutions. The importance of buffers in biological systems, such as the bloodstream, is highlighted. The video concludes with a comprehension check.
