Vedclass · Answer

(C) $TiO_2$ is a widely used white pigment in the paint and coating industry.$MnO_2$ is used as a depolarizer in dry battery cells (Leclanché cells).$UK$ 'copper' coins are primarily made of copper-plated steel or cupronickel alloys,but the statement $(iii)$ as presented is often considered incorrect in the context of standard chemistry curriculum which identifies them as cupronickel or bronze alloys,not simply $Cu/Ni$ in the context of pure extraction examples.Therefore,only $(i)$ and $(ii)$ are correctly matched.

Identify the correctly matched pairs:
$(i)$ $TiO_2$ - pigment industry
$(ii)$ $MnO_2$ - dry battery cells
$(iii)$ $Cu/Ni$ alloy - $UK$ 'copper' coins
