Q. Show Reduction to Metals?
After removed of the gangue, i.e. impurities physically mixed with the metal elements, the concentrated ore becomes ready for the isolation of metal. In concentrated ore, the metals are present in me form of their elements. Extraction of metals involves the reduction of metal compounds to free metals.

These operations are hydrometallurgy, pyrometallurgy, and electrometallurgy.
Acetic acid has less conductivity, due to it ionizes less in solution. HCl divides almost completely in solution to form the ions Cl- and H+..
4-nitrotolouene ---> LiAlH 4 converts it to 4-aminotoluene ----> Add HNO 2 and it forms -----> diazonium salt ------> add H 3 PO 2 to get Toluene -----> add Br 2 /CCl 4 - 2
