Ncert Exercises & Solutions

Match the items of Column I and Column II on the basis of data given below

Column I		Column II
A	F₂	1.	Metal is the strongest reducing agent
B	Li	2.	Metal ion which is the weakest oxidising agent
C	Au³⁺	3.	Non-metal which is the best oxidising agent
D	Br^-	4.	Unreactive metal
E	Au	5	Anion that can be oxidised by Au³⁺
F	Li⁺	6	Anion which is the weakest reducing agent
G	F^-	7	Metal ion which is an oxidising agent

A. F₂ is a non-metal and best oxidising agent because SRP of F₂ is + 2.87 V.

B. Li is a metal and strongest reducing agent because SRP of Li is - 3.05 V.

C. Au³⁺ is a metal ion whichis an oxidising agent as SRP of Au³⁺ is +1.40V.

D. Br^- is an anion that can be oxidised by
Au³⁺ as Au³⁺ (E⁰ = 1.40) is greater than
Br^-(E° = 1.09V).

E. Au is an unreactive metal.

F. Li⁺ is a metal ion having least value ot SRP (- 3.05 V), henceit is the weakest oxidising agent.

G. F^- is an anion which is the weakest reducing ageni as F^- /F₂ has low oxiclation potential (-2.87 V).
