(a)
Interpretation:
Metal or metals in the product should be determined.
Concept introduction:
Reduction potential is the tendency of a chemical species to be reduced in a
(b)
Interpretation:
Probable reaction that occurs should be determined.
Concept introduction:
When two metals in contact, one with the highest reduction potential gets reduced while one with the lower reduction potential gets oxidized.
(c)
Interpretation:
The function of NaHCO3 should be determined.
Concept introduction:
pH is related to the concentration of protons or hydroxyl ions in a solution. Therefore, we can manipulate a driving force of a reaction which involves protons or hydroxyls, by changing the pH of the reaction mixture.
(d)
Interpretation:
How valid the two claims given in the advertisement about the product should be determined.
Concept introduction:
The overall reaction for tarnish removal process by Al is,

- The thermite reaction is 2Al(s) + Fe2O3(s) Al2O3(s) + 2Fe(s) (a) Calculate G for this reaction. (b) Calculate Keq for this reaction. Assume T = 298 K. You may have to do some mathematical manipulations to get your final numerical answer.arrow_forwardHow is the pH scale defined? What range of pH values corresponds to acidic solutions? What range corresponds to basic solutions? Why is pH = 7.00 considered neutral? When the pH of a solution changes by one unit, by what factor does the hydrogen ion concentration change in the solution? How is pOH defined? How arc pH and pOH for a given solution related? Explain.arrow_forwardAn aqueous solution of an unknown salt of vanadium is electrolyzed by a current of 2.50 amps for 1.90 hours. The electroplating is carried out with an efficiency of 95.0%, resulting in a deposit of 2.850 g of vanadium. a How many faradays are required to deposit the vanadium? b What is the charge on the vanadium ions (based on your calculations)?arrow_forward
