Acid Dissociation Constant (Ka):

The Acid Dissociation Constant Calculator is a tool that allows you to calculate the acid dissociation constant (Ka) for a given acid. The calculator takes in three input values: the concentration of the conjugate base of the acid, the concentration of hydrogen ions, and the concentration of the acid (HA). By inputting these values, the calculator can quickly and easily calculate the Ka for the acid.

How it works

The Acid Dissociation Constant Calculator works by using the formula Ka = A * H / HA, where A is the concentration of the conjugate base of the acid, H is the concentration of hydrogen ions, and HA is the concentration of the acid. When you input these values into the calculator and click “Calculate,” the calculator uses this formula to determine the Ka value for the acid.

Formula with examples

The formula for the Acid Dissociation Constant is:

Ka = A * H / HA

Here are some examples to help you understand how to use the formula:

Example 1:

Concentration of conjugate base of acid = 0.2 Concentration of hydrogen ions = 0.0001 Concentration of chemical species (HA) = 0.1

Ka = 0.2 * 0.0001 / 0.1 = 0.0002

Example 2:

Concentration of conjugate base of acid = 0.05 Concentration of hydrogen ions = 0.00001 Concentration of chemical species (HA) = 0.2

Ka = 0.05 * 0.00001 / 0.2 = 0.0000025

Benefits of using the calculator

  • Quick and easy: The calculator makes it easy to calculate the Ka value for an acid without having to do the math manually.
  • Accuracy: By using the formula, the calculator ensures that the Ka value is accurate.
  • Time-saving: The calculator saves time by eliminating the need to manually calculate the Ka value.
