Industrial Applications
Metals like potassium, sodium, calcium, magnesium and aluminium are extracted from their molten ores or salts through this process.
Electrolysis
What will happen in the positive terminal of a chemical cell?
The metal is formed and deposited/receives electron.
A chart showing arrangement of ions in order of electropositivity. They ranks ions to show how easily they donate electrons. What is this chart called?
Electrochemical series
This vast natural resource is mentioned in the textbook as an alternative source to generate electrical energy.
Seawater
In a chemical cell, the metal that "dissolves" into the electrolyte is ?
negative terminal
To make jewelry look more attractive or to prevent rust, metals like gold or silver are coated onto other metals through this process.
Electroplating
A chemical cell is changes what energy to what energy?
!!BONUS!!
Chemical energy to electrical energy
The flow of electrons in a chemical cell always moves in this direction through the external circuit.
negative terminal to the positive terminal
Instead of lab chemicals, these common organic items can be used as a source of chemical energy to build a cell.
Fruits/vegetables
In the electrocoagulation, what gas is released at the cathode in the form of bubbles?
Hydrogen gas
In the process of purifying a metal, the impure metal is always placed at this specific electrode.
Anode
A chemical cell is typically connected to a device to measure the voltage produced. What is the device?
Between Magnesium and Copper, Magnesium becomes the negative terminal because it is _______ than Copper in the electrochemical series.
more electropostive
When using a fruit to make a battery, the fruit's juice acts as what component of a chemical cell?
!!BONUS!!
Electrolyte
A glowing wooden splinter indicates the presence of what gas?
Oxygen gas
During electrocoagulation, aluminium ions and pollutants combine to form these "coagulants" which then float to the surface.
Floc
In a simple chemical cell of Magnesium and Copper, which one will act as the positive terminal.
Copper
If a student uses two strips of the exact same metal, such as two copper strips, the voltmeter will show this reading.
zero
Unlike a chemical cell, an electrolytic cell must have this component to provide it with power.
electrical source (or battery)
These are the three factors that can affect what products are formed during electrolysis?
The position of ions, concentration of electrolyte, and types of electrodes
