• Ques1) Standard electrode potentials are Fe ²⁺ / Fe ( E° = -0.44 V) Fe ³⁺ / Fe²⁺ (E° = 0.77 V) If Fe ²⁺, Fe ³⁺ and Fe blocks are kept together , then (a) Fe³⁺ increases (b) Fe³⁺ decreases (c) Fe²⁺ / Fe³⁺ remains unchanged (d) Fe²⁺ decreases please give explaination as I know the answer is (b) but don't know the reason
• What is Standard Electrode Potential?
• 
• Can a solution of 1 M CuSO₄ be stored in a vessel made of Nickel metal? Given that E⁰ Ni, Ni²⁺ = 0.25 V, E⁰ Cu, Cu²⁺ = - 0.34 V
• The electrode potential of four metallic elements (A, B, C and D) are +0.80V, -0.76V, +0.12V and +0.34V respectively. Arrange them in order of decreasing electropositive character.
• Choose the strongest oxidizing agent among F₂, Br₂, I₂, Cl₂.
• I₂ and Br₂ are added to a solution containing Br^- and I^- ions. What reaction will occur if, I₂ + 2e^-  2I^-; E⁰ = +0.54 V and Br₂ + 2e^-  2Br^-; E⁰ = +1.09 V?
• Is it possible to store Copper Sulphate Solution in a Zinc vessel?
• A solution of silver nitrate was stirred with iron rod. Will it cause any change in the concentration of silver and nitrate ions?
• The standard electrode potentials of a few metals are given below: AI(-0.66V), Cu(+0.34V), Li(-3.05V), Ag(+0.80V) and Zn(-0.76V) Which of these will behave as the strongest oxidizing agent and which as the strongest reducing agent?
