Acids & Bases and introductory REDOX

• arrenhius acids are a substance that produce hydrogen ions in solution, bases produce hydroxide ions in solution
• bronstead lowry acids are anything that donate a proton, bases accept the proton
• conjugate acid-base pairs differ from eachother by a hydrogen ion
• amphiprotic: can either donate or accept a proton
• strong acids completely ionise in solution
• weak acids only partially ionise in solution
• strong bases completely dissociate into hydroxide ions in solution
• weak bases only partially dissociate into hydroxide ions
• h3o+ = hydronium
• Ka = acid ionisation constant
• Kw = ionisation constant for water
• acidic buffers are a mixture of a weak acid and it's conjugate base
• basic buffers are a mixture of a weak base and it's conjugate acid
• buffers are solutions that resist a change in pH
