Final answer:
To calculate the pH and fraction of dissociation for a acetic acid solution, we need to use the initial molarity of the acid and the ionization constant (Ka).
Step-by-step explanation:
To calculate the pH and fraction of dissociation for a acetic acid solution, we need to use the initial molarity of the acid and the ionization constant (Ka). The ionization equation for acetic acid is: CH₃COOH(aq) ⇌ CH₃COO⁻(aq) + H⁺(aq). The fraction of dissociation can be calculated using the ICE table method. For a 0.00161 M solution of acetic acid, the pH can be calculated by taking the negative logarithm of the concentration of the H⁺ ions.
