Final answer:
Yes, a certain buffer solution can prevent an effective electrolysis of CuSO4.
Step-by-step explanation:
Yes, a certain buffer solution can prevent an effective electrolysis of CuSO4. A buffer solution is made up of a weak acid (HA) and its conjugate base (A-). It resists changes in pH when small amounts of acid or base are added.
In the case of electrolysis, when a current is passed through a CuSO4 solution, the Cu2+ ions are reduced at the cathode, causing a decrease in pH. However, if a buffer solution is added, it can help maintain a stable pH and prevent the decrease in pH, thus preventing effective electrolysis of CuSO4.
