Statement-1:In cyanide process for the extraction of gold and silver from their native ores, the cyanide solution acts as a reducing agent to reduce the gold and silver compounds present in the ores, the cyanide solution acts as a reducing agent to reduce the gold and silver compounds present in the ores into the metallic states. Statement-2:In the extraction of gold and silver the cyanide solution acts as complexing reagent in the presence of air and form their respective soluble complexes.

Answer» Statement-1 is TRUE, Statement-2 is True, Statement-2 is a correct EXPLANATION for Statement-1 Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1 Statement-1 is True, Statement-2 is False. Statement-1 is False, Statement-2 is True. Solution :Statement -1 : 4M(s)+`8CN^(-)(aq)+O_2(g)to overset(+I)(4[M(CN)_2]^(-)(aq)+4OH^(-)(aq).` M=Au or Ag. As it is clear from the equation that `CN^(-)` does not acts as reducing agent However `O_2` oxidies metal to metal ION which then react with `CN^(-)` ion to form COMPLEX from which metal is obtained by reduction by more electropositive metal, ZINC,. Statement-2:`4M(s)+8CN^(-)(aq.)+2H_2O(aq)+O_2(g)to overset(+I)(4[M(CN)_2]^(-)(aq)+4OH^(-)(aq).` M=Au or Ag.
