As a lead storage battery is charged.

Write short note on lead storage battery.

Why is a salt bridge not needed in a lead storage battery?

What type of a battery is the lead storage battery? Write the anode and the cathode reactions and the overall reaction occurring in a lead storage battery.

What is a Nickel-Cadmium cell? State its one merit and one demerit over lead storage cell. Write the over all reactions that occurs during discharging of this cell.

Two moles of organic compound 'A' on teratment with a strong base give two compounds 'B' and 'C'. Compound 'B' on dehydrogenation with Cu gives 'A' while acidification of 'C' yield carboxylic acid 'D' with molecular formula of CH_2O_2 . Identify the compounds A, B, C and D. Write all chemical reactions involved.
