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.
when the capacity equals PKa where concentrations of acid and salt are the same that means Log base/acid equals zero
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.
