The formula to calculate the Ionization Percent (P) is:
\[ P = \left( \frac{C_i}{C_0} \right) \times 100 \]
Where:
Let's say the concentration of ionized acid (C_i) is 0.05 M, and the initial concentration of acid (C_0) is 0.1 M. Using the formula:
\[ P = \left( \frac{0.05}{0.1} \right) \times 100 = 50 \% \]
So, the ionization percent is 50%.
