Question

consider the following reaction:
(a) ASO4(aq) + B(s) = BSO4(aq) + A(s)
(b) BSO4(aq) + C(s) = CSO4(aq) + B(s)
(c) CSO4(aq) + A(s) = No reaction
The correct order of reactivity of metals A , B and C is​

Answer 1

Answer:

a) ASO4(aq) + B(s) = BSO4(aq) + A(s)

(b) BSO4(aq) + C(s) = CSO4(aq) + B(s)

(c) CSO4(aq) + A(s) = No reaction

The correct order of reactivity of metals A , B and C is

Answer 2

The correct order of reactivity of metals is C ,B then A.

• Metal Reactivity refers to assembling of metals based on their ability to react with other metals.
• Here, B can displace A in the first reaction. So, B is more reactive than A.
• While, in second reaction, C is more reactive than B so it displaces B from the reaction to form CSO4.
• In third reaction, A cannot replace C. So, it is less reactive than C.
• Hence, the order of reaction goes as C , B then A.
