AI Generated Solution

To solve the question regarding the processes occurring in a lead storage battery while charging, we need to analyze the reactions at both the anode and cathode. ### Step-by-Step Solution: 1. **Understand the Charging Process**: - When a lead storage battery is being charged, the reactions that occur during discharge are reversed. This means that the products formed during discharge will be converted back to their original reactants. 2. **Identify the Components**: ...

Na_(2)CO_(3)+PbSO_(4) to PbCO_(3) darr+Na_(2)SO_(4)

A lead storage cell is discharged which causes the H_(2)SO_(4) electrolyte to change from a concentration of 34.6% by weight (density 1.261gml^(-1) at 25^(@)C ) to one of 27% by weight. The original volume of electrolyte is one litre. Calculate the total charge released at anode of the battery. Note that the water is produced by the cell reaction as H_(2)SO_(4) is used up. over all reaction is. Pb(s)+PbO_(2)(s)+2H_(2)SO_(4)(l)to2PbSO_(4)(s)+2H_(2)O(l)
