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.

∙ 15y agoIt means how much something can resist change.
For example in a drainage system buffer capacity refers to how much water over normal it can take without overflowing.
Or in chemistry a buffer resists change in pH and it's capacity is how much it can do this.

What is the buffer capacity of a solution of a strong base directly proportional to?
The buffer capacity of a strong base is directly proportional to the concentration of hydroyxl ions. Buffer capacity = 2.303 x [OH-]
Does buffer capacity depend on the amount of buffers present?
Yes. The higher the number of buffers, the higher the buffer capacity.
What happens to the buffer a pH capacity?
The buffer maintain the pH constant.
What non living factors effect carrying capacity in a lake?
food, water, population
What two factors are involved in determining the exact pH of a buffer?
The molarity of the buffer and the hydrogen concentration of the buffer.
Effect of Diluting a buffer?
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.
What factors determine the buffering capacity of a solution?
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.
Why doesn't the rectum have buffer capacity?
The rectum doesn't have enough fluids to have buffer capacity.
How temperature can effect the buffer capacity?
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,
What is the buffer capacity of a solution of a strong base directly proportional to?
The buffer capacity of a strong base is directly proportional to the concentration of hydroyxl ions. Buffer capacity = 2.303 x [OH-]
Does buffer capacity depend on the amount of buffers present?
Yes. The higher the number of buffers, the higher the buffer capacity.
What happens to the buffer a pH capacity?
The buffer maintain the pH constant.
When does a buffer have its greatest buffer capacity?
when the capacity equals PKa where concentrations of acid and salt are the same that means Log base/acid equals zero
Does buffer capacity change with temperature?
Yes
What is the buffer capacity of a solution of a strong acid directly proportional to?
It is directly proportional to the concentration of hydrogen ions. Buffer capacity = 2.303 x [H3O+]
What non living factors effect carrying capacity in a lake?
food, water, population
What two factors are involved in determining the exact pH of a buffer?
The molarity of the buffer and the hydrogen concentration of the buffer.
