Ibn the cyanide extraction process of silver form aragetite are ,oxidizing and reduction agents used are action .

Options

A. `HNO_(3) and CO` respectively
B. `HNO_(3) and Zn` respectively
C. `O_(2) and Zn` dust respectively
D. `O_(2) and CO` respectively

Answer

c

Explanation

The reaction involved cyaride extraction process atc
`underset("Argentide")(Ag_(2)S) + 4NaCN to Na [Ag(CN)_(2)] + Na_(2)S`
Air in blow into the mixture to oxide the stadium sulphide to outplate .This makes the reversible reaction to procced completely to the right
`4Na_(2)S + underset({:("Oxidizing"),("agent"):})(5O_(2)) + 2H_(2)O to 2NaSO_(4) + 4NaOH + 2S`
The silver is perciptant from the solution by adding zine metal.
`2Na [Ag(CN)_(2)] + underset({:("Reducing"),("agent"):})(Zn) to [Zn(CN)_(4)] + 2Ag`
