Cold acid IV, Hot acid pb NR. Mg Ne NR VF Very Fast reaction rate S Slow reaction rate NR No Reaction F Fast reaction rate VS Very Slow reaction rate Metal Displacement Reactions Copper (Cu) Lead (Pb) Tin (Sn) Zinc (Zn) Cu Mg Sn R Reaction NR -No Reaction Analysis (A) IV. Based on the aqueous reaction Data (not necessarily following Fig. 1), list the metals belonging in each category. (Not all spaces will be needed for all categories) Category 1. Displaces H2 from cold water Category 2. Displaces H2 from hot water Category 3. Displaces H2 from cold aqueous acid (Ca included though not tested) Category 4. Displaces H2 from hot aqueous acid (Ca included though not tested)Explanation / Answer
Displacement reactions
I. IIV. based on this experiment
Category 1 : metal displacing H2 from cold water
Cu
Category 2 : metal displacing H2 from hot water
Sn
Category 3 : metal displacing H2 from cold aqueous acid
Fe
Category 4 : metal displacing H2 from hot aqueous acid
Fe, Mg, Sn and Zn
V. Count the number of different metal ions that reacted with each metal
Copper (Cu) : 3
Lead (Pb) : 3
Tin (Sn) : 4
Zinc (Zn) : 5
Based on the reactivity the activity of different metal ions would be,
Most active metal : Ag+ > Fe3+ > Cu2+ > Pb2+ > Sn2+ > Mg2+ : least active metal
Combining VI and V (and not including Ca)
most active metal : Ag+ > Fe3+ > Cu2+ > Pb2+ > Sn2+ > Zn2+ > Mg2+ : least active metal
