Activity Series (HSC SSCE Chemistry): Flashcards

Metals ordered by decreasing chemical reactivity

$\text{K>Na>Li>Ba>Ca>Mg>Al>Zn>Fe>Sn>Pb>H>Cu>Ag>Pt>Au}$

K, Na, Li, Ba, Ca (left of series)

Cu, Ag, Pt, Au (right of series)

Between Pb and Cu

React to displace hydrogen gas

More reactive metal displaces less reactive from solution

K, Na, Li, Ca, Ba only

Distinguish metals with equal reactivity

Yes, Fe is more reactive (left of Cu)
