Question

What is a reactivity series? Draw a flow chart for extraction of metals in the lower, middle and higher order of reactivity. How is mercury extracted from its ore Cinnabar?

Answer 1

The series in which metals of non metals are arranged in the decreasing order of reactivity.

highly reactive metal (K, Ca, Na, Mg, Al) :- Extraction by electrolysis

Moderately reactive metals( Zn, Fe, Pb, Cu) :- By reduction of oxide with carbon (coke)

Less reactive:-(Cu, Hg) :- By self reduction of Sulphide ore( by heat alone

Least reactive (Ag, Pt, Au) :- Found in natural state

mercurey is extracted by heat alone

hope it helps

Answer 2

Answer:

the arrangement of metals in the vertical column in the order of decreasing reactivity is called reactivity series. thanks like this and follow
