What is the purpose of the salt bridge in a galvanic cell?

• To provide a site for reduction

• To maintain electrical neutrality

• To complete the circuit

• To provide a site for oxidation

The Ag(s) and Ag²⁺ (aq) species are called a

• Electrode

• Salt bridge solution

• Conjugate redox pair

• Golden Duck

Iron is undergoing ........

• oxidation

• reduction

• neutralisation

• oxidation and reduction

Which of the following is a characteristic of a redox reaction?

• Transfer of protons

• Transfer of electrons

• Formation of water

• Formation of salt

In a galvanic cell, the anode is the electrode where

• oxidation occurs

• reduction occurs

• no reaction occurs

• both oxidation and reduction occur

Potassium Nitrate (KNO₃) is often used as the chemical in a salt bridge, what direction will the potassium ions move in the cell shown

• towards the s electrode

• towards the q electrode

• they will not move and remain in the salt bridge

Potassium Nitrate (KNO₃) is often used as the chemical in a salt bridge, what direction will the nitrate ions move in the cell shown

• towards the s electrode

• towards the q electrode

• they will not move and remain in the salt bridge

A galvanic cell converts​ (a)   energy into ​ (b)   energy using redox reactions. The anode will be the site of ​ (c)   where electrons are ​ (d)   and the cathode will be the site of ​ (e)   where the electrons are received.
