Oxidation-reduction reaction - Correct Answer ✔✔ the transfer of electrons
Oxidation-reduction reaction - Correct Answer ✔✔ the transfer of electrons
What is the oxidation half-reaction?
2 AgCl → 2 Ag + Cl2 - Correct Answer ✔✔ 2 Cl- → Cl2 + 2 e-
(Oxidation is the loss of electrons and the chloride ions lose electrons to become
chlorine gas)
What is the reducing agent?
2 AgCl → 2 Ag + Cl2 - Correct Answer ✔✔ Cl-
The nitrogen atom in ammonia (NH3) is being...
NH3 + O2 → NO2- + 3 H+ - Correct Answer ✔✔ Oxidized
How does the ionization energy correlate to an element's redox chemical reactivity? -
Correct Answer ✔✔ An element with a high ionization energy tends to get reduced
because it does not want to give up electrons.
The following set of redox reactions take place as shown as part of a voltaic cell:
Container A Container B
Fe → Fe2+ + 2e- 2 Li+ + 2e- → 2 Li
Consider a situation where the pieces of metal in each container are connected via a
wire, but there is no salt bridge connecting the containers. What happens? - Correct
Answer ✔✔ A little bit of iron is converted into iron ions and a little bit of the lithium ions
are converted into lithium metal.
The following set of redox reactions take place as shown as part of a voltaic cell:
Container A Container B
Fe → Fe2+ + 2e- 2 Li+ + 2e- → 2 Li
Assume the voltaic cell is complete and possesses all required components to function
properly. In which direction will the cations in the salt bridge flow and why? - Correct
Answer ✔✔ Towards the solution containing Li+ ions to balance the change in charge
due to loss of Li+ ions as the reaction progresses.
Which of the following is not a true statement about voltaic cells? - Correct Answer ✔✔
Electrodes must be reactants in the redox reactions.
In a particular battery, the below oxidation-reduction reaction takes place. What is
formed at the anode?
