PH buffers are special solutions which prevent large variations in pH levels. Every pH level produced has a specified buffer capacity and buffer range. The capacity of the buffer refers to the amount of acid or base which can be added before the pH alters substantially. It may also be characterized as the level of strong acid or base that needs to be added to alter the pH of a liter of solution by one pH unit. The buffer range is the pH range where a buffer can effectively neutralize added acids and bases whilst maintaining a steady pH. This is critical for processes or reactions which need specific and stable pH ranges.
Using pH Buffers to Achieve Accurate Measurements
All experienced chemists will be extremely confident with the idea of pH value. The pH value of a substance pertains to the negative logarithm of hydrogen ion activity. Sometimes this is known as the potential of hydrogen in an aqueous solution. The pH of a solution is on a scale of 0-14 and is
