Reactivity Series
1. This question has 3 part(s).
1.1. The reactions of metals with water and with dilute sulfuric acid can be used to determine the order of reactivity of the metals.
The table shows the reactions of four metals, W, X, Y and Z, with water and with dilute sulfuric acid.
Metal | Reaction with water | Reaction with dilute sulfuric acid |
W | no reaction | no reaction |
X | very slow reaction | reacts quickly |
Y | no reaction | reacts slowly |
Z | reacts quickly | reacts violently |
What is the order of reactivity of these metals?
most reactive | least reactive | |||
A | W | X | Y | Z |
B | Z | X | Y | W |
C | W | Y | X | Z |
D | Z | Y | X | W |
1.2. i) State which metal, W, X, Y or Z, could be copper.
(1)
ii) State which metal, W, X, Y or Z, could be magnesium.
(1)
1.3. A displacement reaction can also be used to decide the order of reactivity of two metals.
State two observations made when an excess of magnesium powder is added to an aqueous solution of copper(ll) sulfate.
