Concept explainers
Interpretation:
The sacrificial anode has to be given with an example.
Concept Introduction:
Corrosion:
The change in surface of certain metallic objects when left unused for longer period time is called as corrosion. Corrosion leads to the slow degradation of the metal. Rusting is one of the ways of corrosion in metals. It can generally be seen in iron and its alloys.
Corrosion of any metal is natural process. It results in the conversion of metal to its chemically stable that could be either oxides or hydroxides or sulphides.
Cathodic protection:
Cathodic protection is a technique that is used to control the corrosion of metal surface by making it the cathode of

- Give the notation for a voltaic cell whose overall cell reaction is Mg(s)+2Ag+(aq)Mg2+(aq)+2Ag(s) What are the half-cell reactions? Label them as anode or cathode reactions. What is the standard cell potential of this cell?arrow_forwardUse chemical equations to explain how the molten carbonate fuel cell (MCFC) works. What are its advantages and its disadvantages?arrow_forwardFor a voltage-sensitive application, you are working on a battery that must have a working voltage of 0.85 V. The half-cells to be used have a standard cell potential of 0.97 V. What must be done to achieve the correct voltage? What information would you need to look up?arrow_forward
