How to Use the Henderson Hasselbalch Calculator?

The procedure to use the Henderson Hasselbalch calculator is as follows:

Step 1: Enter the molar concentration of the conjugate base, acid, dissociation constant in the input field

Step 2: Now click the button “Calculate pH” to get the result

Step 3: Finally, the hydrogen ion concentration of the buffer solution will be displayed in the output field

What is Meant by Henderson Hasselbalch Equation?

In chemistry, the Henderson Hasselbalch equation is used to calculate the hydrogen ion concentration (pH) of the buffer solution. We know that the solution consists of a strong acid and a weak conjugate base or the strong base and weak conjugate acid. We can say that an acid is a proton donor and the base is a proton acceptor. The Henderson Hasselbalch equation to calculate the hydrogen ion concentration is

pH = pK_a + log ([A^–]/[HA])

Where

[A^–] is the molar concentration of conjugate base

[HA] is the molar concentration acid

pK is the acid dissociation constant.
