How do you calculate the total buffer capacity of an aqueous solution of a strong base or base at any pH?

Buffer capacity depends on the Ka of the buffer component, the concentration of the buffer (C), as well as the [H3O+]. Thus, it will be
Buffer capacity = 2.3 C (Ka x [H3O+]/(Ka + [H3O+])^2
The Ka will be that of the conjugate acid and [H3OP+] will be the antilog of -pH. Then just plug and chug.

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-]
What is buffer capacity and what are the factors that effect the buffer capacity?
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.
What is the importance of a buffer?
A buffer helps prevent radical changes in pH of a solution by providing a means for which an acid or base that may find its way into the solution to be able to react. Buffers are made up or strong or weak acids and their salts. Together in aqueous solution, their pH will remain relatively the same despite adding acid or base. However once the buffer has fully reacted in either direction, the pH will then be subject to radical shifts in value.
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 does the dilute aqueous solution of a weak base contains?
buffer solution
What is buffer action?
Chemical Buffer Action regarding Acids and Bases: this means that when an aqueous solution is buffered, adding small amounts of H+ or OH- to the solution will not change the solution's pH.
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-]
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.
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+]
How does osmolarity affect buffer capacity?
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.
Is distilled water buffered?
No, distilled water is not a buffer. A buffer is an aqueous solution consisting of a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid.
A solution that is resistant to change in pH?
Solutions that resist change in pH when added to a strong acid or base are known as buffer solutions.
How osmolarity affect buffering capacity?
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.
What is pseudo buffer?
a solution which does not fulfills the property of a buffer solution but act as buffer solution.
