C3.4 Electrolysis

Question 1

What is electrolysis?

Answer 1

The process in which a electric current is passed through a compound to decompose it or to cause a change

Question 2

What is the definition of electrolyte?

Answer 2

A compound which is in liquid state and contains mobile ions which can conduct electricity

Question 3

What are electrodes?

Answer 3

Electrodes are rods usually made from an unreactive metal or graphite which conduct electricity to the electrolyte. They can either be inert or non inert

Question 4

What is the negative terminal called and which ions go to it?

Answer 4

Cathode and it attracts positive ions(cations) which gain electrons to become atoms

Question 5

What is the positive terminal called and which ions go to it?

Answer 5

Anode and it attracts positive ions(anions) to lose electrons to become atoms

Question 6

From left to right(diagram)

Answer 6

Cathode(negatively charged), anode (positively charges)

Question 7

What is a binary compound?

Answer 7

A compound with JUST 2 ions or elements

Question 8

What does a discharges ion mean?

Answer 8

An ions that has become an atom or molecule

Question 9

Where do ions move in electrolysis?

Answer 9

To the electrode which is opposite to their charge

The LEAST reactive element goes to the electrode and HALIDES TAKE PRIORITY
