The PH ScaleThe pH Scale is a measurement of how acidic or how basic a solution is.

The scale goes from 0 to 14.

The PH ScaleCompounds are acidic if they have a pH lower than 7.

Compounds with a pH higher than 7 are basic or alkaline.

Compounds with a pH of 7, are neutral.

BuffersA buffer is a weak acid or base that prevents sudden changes in pH.Maintains homeostasis

Page 36: Water

BuffersA buffer works by binding to H+ ions releasing H+ ions when the solution pH changes.

BuffersBuffers bind to H+ ions when the concentration of H= ions in solution increases.
