Question

*6. Nickel is below iron but above lead in the reactivity
series. Aqueous solutions of nickel compounds are
green.
(a) Predict the observations and write the
chemical equation for the reaction that takes
place when
(1)nickel is added to dilute hydrochloric
acid;
(11) nickel is heated with steam.
(b) Predict what happens when nickel is
(1) heated with magnesium oxide;
(11)added to copper(ll) nitrate solution.
(c) (1) From the reactions in (b)(i) and (b)(ii),
state which of these metals, nickel,
magnesium and copper, has the highest
tendency to form its positive ions.
(11) Based on their tendency to form
positive ions, deduce the positions of
magnesium and copper with respect to
nickel in the reactivity series.​
