What is buffer solution?

A buffer solution (more precisely, pH buffer or hydrogen ion buffer) is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. Its pH changes very little when a small amount of strong acid or base is added to it.

How to Calculate Buffer Capacity?

Buffer Capacity calculator uses Buffer Capacity = Number of Moles of Acid or Base/Change in pH to calculate the Buffer Capacity, The Buffer Capacity formula is defined as a quantity in resisting the pH change at the time of addition of an acid or base. The higher the acid concentration of the buffer then the buffer capacity will be higher as well. Buffer Capacity is denoted by β symbol.

How to calculate Buffer Capacity using this online calculator? To use this online calculator for Buffer Capacity, enter Number of Moles of Acid or Base (n_a/b) & Change in pH (d_pH) and hit the calculate button. Here is how the Buffer Capacity calculation can be explained with given input values -> 25 = 10/4.

FAQ

What is Buffer Capacity?

The Buffer Capacity formula is defined as a quantity in resisting the pH change at the time of addition of an acid or base. The higher the acid concentration of the buffer then the buffer capacity will be higher as well and is represented as β = n_a/b/d_pH or Buffer Capacity = Number of Moles of Acid or Base/Change in pH. Number of Moles of Acid or Base added in the solution to change the pH value & Change in pH gives the change in the pH value of the solution when acid or base is added.

How to calculate Buffer Capacity?

The Buffer Capacity formula is defined as a quantity in resisting the pH change at the time of addition of an acid or base. The higher the acid concentration of the buffer then the buffer capacity will be higher as well is calculated using Buffer Capacity = Number of Moles of Acid or Base/Change in pH. To calculate Buffer Capacity, you need Number of Moles of Acid or Base (n_a/b) & Change in pH (d_pH). With our tool, you need to enter the respective value for Number of Moles of Acid or Base & Change in pH and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
