Suppose that gold is being plated on to another metal in an electrolytic cell. The half - cell reaction producing the Au(s) is AuCl_(4)^(-)+3e^(-)+Au(s)+4Cl^(-) . If a 0.30 A current runs for 15.00 minute, what mass of Au(s) will be plated, assume all the electrons are used in the reduction of AuCl_(4)^(-) ? the Faraday constant is 96485 C/mol and molar mass of Au is 197.

A constant current was passed through a solution of AuCl_(4)^(c-) ion between gold electrodes. After a period of 10.0 mi n , the increase in the weight of cathode was 1.314g . The total charge passed through solution is ( atomic weight of AuCl_(4)^(c-)=339)

The reduction potential of the two half cell reactions (occuring in an electrochemical cell) are PbSO_(4)+ 2e^(-)rarrPb+SO_(4)^(2-) (E^(@)=-0.31V) Ag^(+)(aq)+e^(-)rarrAg(s)(E^(@)=+0.80V) The fessible reaction will be

The reduction potential of the two half cell reaction (occurring in an electrochemical cell) are PbSO_(4)(s)+2e^(-)rarrPb(s)+SO_(4)^(2-)(aq)(E^(@)=-0.31V) Ag^(+)(aq)+e^(-)rarrAg(s)(E^(@)=0.80V) The feasible reaction will be

Which expression gives the correct value of the standard potential for a gold-rhodium voltaic cell? {:("Half-reaction",E^(@)V), (Rh^(3+)(aq) +_ 3e^(-) rightarrow Rh(s), 0.76), (Au^(+)(aq) + e^(-) rightarrow Au(s), 1.69):}

The standard electrode potential corresponding to the reaction Au^(3+)(aq)+3e^(-)rarrAu(s) is 1.50 V predict if gold can be dissolved in 1M HCI solutoin and on passing hydrogen gas through god salt solution metallic gold will be precipitated or not

Titanium metal is extensively used in aerospace industry because the metal imparts strength to structures but does not unduly add to their masses. The metal is produced by the reduction of TiCl_(4(l)) which in turn is produced from mineral rutile [TiO_(2(s))] . can the following reaction for production of TiCl_(4(l)) be carried out at 25^(@)C ? TiO_(2(s))+2Cl_(2(g))toTiCl_(4(l))+O_(2(g)) Given that H_(f)^(@) for TiO_(2(s)),TiCl_(4(l)),Cl_(2(g)) and O_(2(g)) are -944.7, -804.2,0.0,0.0 kJ mol^(-1) . also S^(@) for TiO_(2(g)),TiCl_(4(l)),Cl_(2(g)) and O_(2(g)) are 50.3,252.3,233.0,205.1 J mol^(-1) K^(-1) respectively.
