Concept explainers
Interpretation:
The term ‘rusting’ from the molecular viewpoint is to be explained.
Concept Introduction:
Oxidation is the addition of an electronegative element or the removal of an electropositive element in the
Reduction is the addition of an electropositive element or the removal of an electronegative element in the chemical reaction.
The chemical reaction in which oxidation and reduction take place simultaneously is called a redox reaction.
An oxidizing agent is a substance that has the capacity to oxidize the other substances and get reduced in a chemical reaction.
A reducing agent is a substance that has the capacity to reduce the other substances and get oxidized in a chemical reaction.

- • calculate the amount of metal plated, the amount of current needed, or the time required for an electrolysis process.arrow_forwardA factory wants to produce 1.00 103 kg barium from the electrolysis of molten barium chloride. What current must be applied for 4.00 h to accomplish this?arrow_forwardAn aqueous solution of an unknown salt of gold is electrolyzed by a current of 2.75 amps for 3.39 hours. The electroplating is carried out with an efficiency of 93.0%, resulting in a deposit of 21.221 g of gold. a How many faradays are required to deposit the gold? b What is the charge on the gold ions (based on your calculations)?arrow_forward

How do you know? b Does current flow in this cell spontaneously? c What is the maximum cell potential for this cell? d Say the cell is connected to a voltmeter. Describe what you might see for an initial voltage and what voltage changes, if any, you would observe as time went by. e What is the free energy of this cell when it is first constructed? f Does the free energy of the cell change over time as the cell runs? If so, how does it change?arrow_forwardZinc is produced by electrolytic refining. The electrolytic process, which is similar to that for copper, can be represented by the two half-reactions Zn(impure,s)Zn2++2eZn2++2eZn(pure,s) For this process, a voltage of 3.0 V is used. How many kilowatt hours are needed to produce one metric ton of pure zinc?arrow_forwardBalance the following skeleton equations.

- The mass of three different metal electrodes, each from a different galvanic cell, were determined before and after the current generated by the oxidation-reduction reaction in each cell was allowed to flow for a few minutes. The first metal electrode, given the label A, was found to have increased in mass; the second metal electrode, given the label B, did not change in mass; and the third metal electrode, given the label C, was found to have lost mass. Make an educated guess as to which electrodes were active and which were inert electrodes, and which were anode(s) and which were the cathode(s).arrow_forwardGold is produced electrochemically from an aqueous solution of Au(CN)2 containing an excess of CN. Gold metal and oxygen gas are produced at the electrodes. What amount (moles) of O2 will be produced during the production of 1.00 mole of gold?arrow_forwardDetermine the overall reaction and its standard cell potential at 25 C for these reactions. Is the reaction spontaneous at standard conditions? Assume the standard reduction for Br2(l) is the same as for Br2(aq).. Pt(s)|H2(g)|H+(aq)Br2(aq),Br(aq)|Pt(s)arrow_forward
