How to Calculate Ka from a Graph

\n

Understanding how to calculate the acid dissociation constant (Ka) from experimental data is fundamental in chemistry. Ka quantifies the strength of an acid in solution, and obtaining it from a concentration vs. time graph involves analyzing the changes in hydronium ion concentration over time. This guide will walk you through the process step-by-step.

What is Ka?

\n

The acid dissociation constant, Ka, is a measure of the strength of an acid in solution. For a weak acid HA dissociating in water, the equilibrium can be represented as:

\n

\nHA(aq) + H2O(l) ⇌ H3O+(aq) + A-(aq)\n

\n

The Ka expression is given by:
