What are buffer solution and buffer capacity?
buffer capacity is the amount of acid or base that can be absorbed by a buffer solution without any significant change
it is defined the capability of a buffer to resist the change of pH.it can be measured quantity that how much extra acid or base , the solution can absorb before the buffer is essentially destroyed. buffer capacity of a buffer solution is determined by the sizes of actual molarities . so , a chemist must decide before making the buffer solution.
The buffer capacity increases as the concentration of the buffer solution increases and is a maximum when the pH is equal to the same value as the pKa of the weak acid in the buffer. A buffer solution is a good buffer in the pH range that is + or - 1 pH unit of the pKa. Beyond that, buffering capacity is minimal.
Buffer capacity refers to the amount of strong acid or strong base that can be added to any solution before it changes the pH level by one. Osmolarity is the measure of how much of a soluble substance is present in any solution. Buffer capacity can be managed in a solution then by changing the osmolarity of solubles that affect buffering ability.
How do you calculate the total buffer capacity of an aqueous solution of a strong base or base at any pH?
Buffer solutions are chemicals that react in both acidic and alkaline chemicals to neutralize them. They are often used to create a neutral solution when calibrating a pH meter. High temperatures can degrade a buffer solution, reducing its effectiveness. Ph meters are also effected by temperatures, so it is essential to follow the manufacturer's instructions about the temperatures when calibrating them,
A buffer solution is one involving a weak base/weak acid with its conjugate acid/base. In a buffer solution, the pH must be changed to only a small amount. Thus, any solution with a STRONG acid or a STRONG base is not a successful buffer solution because there would be a relatively large change in the initial pH.
When dealing with PH buffers, anything you add to the solution can change the PH of the solution. If it was more specific I could tell you exactly why, what are you diluting the buffer with? do you have a PH meter to see the actuality of what your doing? or trying to do? What is your Buffer solution?
