relative reactivity of metal
Answers
Answer:
The relative reactivity of a group of metals can be established by comparing the reaction of each metal with a given reagent. A metal might react with a specific reagent or no reaction may occur. On the other hand, a given metal might react with a specific reagent at a different rate than some other metal.
In this experiment, the reaction of a group of metals with dilute hydrochloric acid will be used to determine the relative reactivity of the metals. Some metals react with dilute hydrochloric acid as shown in Equation (1).
(Equation. 1) M(s) + 2 HCl(aq) ---> MCl2(aq) + H2(g)
At the same time, the rate at which different metals react with dilute hydrochloric acid will vary. Thus, from the laboratory observations as to whether a gas is formed and if so at what rate the gas is evolved, the relative reactivity of the metal can be determined.
A second reaction to be studied in this experiment is the reaction of each of a group of metals with solutions of their corresponding salts. Some metals will react with a solution of a salt of another metal as indicated in Equation (2).
(Equation. 2) M(s) + FeSO4(aq) ---> MSO4(aq) + Fe(s)
In this case, the fact that a metal does or does not rect with a solution of another metallic salt can be used to establish the order of reactivity of a group of metals
