Write reactions involved in extraction of silver from it's ore by leaching process. O-nitrophenol is more acidic than O-cresol; Explain.

leaching process for silver.

Ortho nitrophinol is morl acidic then cresol bcoz

the nitro groups is an electron -withdrawing graph the presence of this group in the ortho  posn in $O-$nithophenol  decreases the election in the $O-H$ bond. as a result, it is easier to loss a proton.

In case of $O-$cresol, methony groups is an edg yhus it increases the $e^{-}$ density in the $O-H$ bond and hence, the proton cannot be given out easily.
