chapter 5 electrochemistry class 12 chemistry textbook solution

    3. Answer the following in brief

    x. Why do the cell potential of lead accumulators decrease when it generates electricity ? How the cell potential can be increased ?

    Answer:-

    1. The cell potential is influenced by the concentration (density) of sulfuric acid. When the cell operates to generate current, H₂SO₄ is used up. This causes a decrease in its concentration (density), leading to a reduction in the cell potential.
    2.  During the recharging process, when an external potential slightly greater than 2 V is applied, H₂SO₄ is regenerated. Consequently, its concentration (density) increases, resulting in an increase in the cell potential.
