NCERT Solutions for Class 8 Science Chapter 11 Topics

11.1 Do Liquids Conduct Electricity?: All liquids conduct electricity. However, not all liquids conduct electricity. The conductivity of a liquid depends on whether it allows the flow of ions (charged particles) through it.

11.2 Chemical Effects of Electric Current: As discussed in chapter 11 science class 8 NCERT solutions pdf download, Electrolysis is the chemical reaction that occurs when an electrical current passes through a substance. Electrolysis has a wide range of applications, from electroplating to water purification and chemical production.

11.3 Electroplating: As discussed in chapter 11 science class 8 NCERT solutions pdf download Electroplating, also known as electrolysis, is the process of depositing a thin layer of a metal onto the surface of other metal objects. Electroplating is widely used in industry and for decorative applications to improve the look, resistance to corrosion, and longevity of objects.

Key Features of Class 8 Science Chapter 11

The key features of the chemical effects of electric current, also known as electrolysis, include: 

Electrolyte & Ions: Electrolysis involves the use of an electrolyte, a solution of ions of a substance that is electroplated or broken down. The electrolyte may be a liquid or molten compound. The electrolyte is the source of the ions involved in the chemical reactions.

Anode & Cathode: The electrolysis process involves two electrodes: an anode and a cathode. Each electrode is connected to a positive terminal of a power source. Each electrode has a specific function in the electrolysis process.

Redox & Reduction: Redox reactions occur simultaneously in the anode and cathode of an electrolysis. In the anode, the oxidation reaction occurs as the negatively charged ion (anion) loses electrons and forms a neutral atom or molecule. In the cathode, the redox reaction occurs as the positively charged ion (cation) gains electrons and forms an atom or molecule.

Deposition and Dissolution: Depending on the reaction, the anode or cathode may be either deposited (reduced metal ions are deposited onto cathode) or dissolved (reduced metal at anode is dissolved into the electrolyte in the form of ions).

Change in Electrodes: As the process of electroplating (or electrolysis) progresses, the size of the anode may decrease over time as the metal is dissolved in the electrolyte, and the cathode collects a layer of the plated metal.

Control of Thickness: Parameters such as the process time, current density and electrolyte concentration can affect the thickness of plated metal in electroplating.

Frequently Asked Questions

Question 1: What are the chemical effects of electric current?

Answer 1: As discussed in class 8 science chapter 11 chemical effects of electric current NCERT solutions pdf, Electrolysis is the process by which an electrolyte is broken down into its component ions. Electrolysis occurs when an electric current flows through the electrolyte. Electrolysis results in chemical reactions at the electrodes, such as oxidation and reduction.

Question 2: What is an electrolyte?

Answer 2: As discussed in class 8 science chapter 11 chemical effects of electric current NCERT solutions pdf, Electrolytes are substances that are able to conduct electricity because they contain ions. They're usually in the form of either a solution or a liquid and are necessary for the process of electrolysis.
