Growth Technology - Buffer 7 - 1L - PH Buffer Calibration
Solutions of a known and fixed ph. These are used to calibrate pH meters. This should be done on a regular basis to ensure ongoing accuracy from the meter.
Buffers & Buffer Solutions:
Buffers are substances that minimize changes in concentrations of ions i.e. either H+ ions or OH- ions. A buffer solution is that which resists changes in pH and whose pH is not altered to any great extent by the addition of small quantities of either strong acid (H+ ions) or a strong base (OH– ions) is called the buffer solution.
The composition of a buffer:
The buffer in acidic range is a mixture of a weak acid and salt of conjugate base of the weak acid. And a buffer in a basic region is a mixture of weak base and salt of conjugate acid of weak base.
Le Chatelier’s Principle and working of buffers:
We have studied years earlier in FSc a principle called Le Chatelier’s principle. All buffers work on Le Chatelier’s principle. Le Chatelier’s Principle states that the left and right side of the reaction prefer a certain balance or ratio between themselves. We know that many chemical reactions are reversible. As we talk about weak acid in buffer solutions generally so we take an example of a weak acid.
