A buffer is a mixture of molecules that release or bind H+ in order to maintain a relatively stable pH. Note that the function of a buffer is NOT to keep a solution neutral (at pH 7); its function is to minimize the change in pH when base or acid is added to the solution. Also note that there are many different buffers, and each one will stabilize the pH of a solution only within a specific pH range.

Heidi Klum posted a rare picture with her father to Instagram on Monday. In the snap, the 42-year-old supermodel is seen dining with her 69-year-old dad GÃ¼nther, who doesn't look much older than the star. They appear to be in a hotel room and the mother-of-four pointed out they were in Munich, Germany.
