The mass of P b S O 4 consumed in a lead storage battery should be calculated. Concept Introduction: Electrolysis is a process in which positively charged metal ions migrate towards the cathode (negative electrode). These ions are reduced at the cathode to form neutral metal atoms which are deposited on the cathode. The same process occurs in a lead storage battery in which lead is deposited at the cathode. The mass of lead deposited on the electrode after a certain interval of time can be calculated by applying Faraday’s laws of electrolysis.

Question

Chapter 13, Problem 13.89PAE

Interpretation Introduction

Interpretation: The mass of PbSO4 consumed in a lead storage battery should be calculated.

Concept Introduction:

Electrolysis is a process in which positively charged metal ions migrate towards the cathode (negative electrode). These ions are reduced at the cathode to form neutral metal atoms which are deposited on the cathode. The same process occurs in a lead storage battery in which lead is deposited at the cathode.

The mass of lead deposited on the electrode after a certain interval of time can be calculated by applying Faraday’s laws of electrolysis.
