Assignment:
Question 1. Recognize the effect common ions exert on acid ionization and pH, and mechanisms by which solutions are buffered by ions.
Question 2. Examine acid base titration and the Henderson-Hasselbalch equation and calculate the pH of a system at any stage of titration involving both strong and weak acid bases.
Question 3. Apply Le Chatelier's Principle to explain the effects of common ions and pH on solubility.
Question 4. Describe the effect of complex ion formation on solubility.
Provide complete and step by step solution for the question and show calculations and use formulas.
