Untitled Flashcards Set

Conductors

Materials that allow electric current to flow through them easily.

Insulators

Materials that do not allow electric current to flow through them easily.

Electrolytes

Liquids that conduct electricity, consisting of charged particles called ions.

Non-Electrolytes

Liquids that do not conduct electricity, such as distilled water and sugar solutions.

Anode

The electrode connected to the positive terminal of a battery where oxidation occurs.

Cathode

The electrode connected to the negative terminal of a battery where reduction occurs.

Electrolysis

The process of decomposing a substance in liquid state into its ions by passing electric current.

Electrolytic Refining of Copper

A process of purifying copper based on electrolysis, using impure copper as anode and pure copper as cathode.

Electroplating

Coating a surface with a thin layer of metal using electrolysis.

Factors Affecting Electroplating Thickness

The thickness of electroplating depends on current strength, metal ion concentration, and duration of electroplating.

Hydrogen ions (H+) and Hydroxide ions (OH-)

Ions produced during the electrolysis of water.

Cations

Positively charged ions that migrate toward the cathode.

Anions

Negatively charged ions that migrate toward the anode.

Uses of Electrolysis

It is used in metal extraction, refining, electroplating, producing gases, and in submarines for breathing.

Electrolyte for Copper Sulphate Solution

The solution used in electrolytic refining of copper, dissociating into copper and sulfate ions.

Electrolytic Process Observation

Observation of gas bubbles at electrodes during electrolysis reflects the decomposition of the liquid.
