because it resists change of ph of acid and base
The rectum doesn't have enough fluids to have buffer capacity.
The buffer capacity of a strong base is directly proportional to the concentration of hydroyxl ions. Buffer capacity = 2.303 x [OH-]
Yes. The higher the number of buffers, the higher the buffer capacity.
The buffer maintain the pH constant.
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.
Yes
It is directly proportional to the concentration of hydrogen ions. Buffer capacity = 2.303 x [H3O+]
The concentration of the buffer (the higher the concentration, the larger the buffering capacity) and how close the pKa of the buffer is compared to the pH of the solution (the closer the greater the buffer capacity).See the Related Questions to the left for more information on buffers.
A buffer has its greatest buffer capacity when the concentrations of the weak acid and its conjugate base are approximately equal. This is because the buffer system can efficiently resist changes in pH when there are similar amounts of the weak acid and conjugate base available to neutralize added acid or base.
Bicarbonate Buffer System (only important ECF buffer)
Buffer capacity depends on the Ka of the buffer component, the concentration of the buffer (C), as well as the [H3O+]. Thus, it will beBuffer capacity = 2.3 C (Ka x [H3O+]/(Ka + [H3O+])^2The Ka will be that of the conjugate acid and [H3OP+] will be the antilog of -pH. Then just plug and chug.
