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.

Higher the electrode potential (E0) lower is the tendency of the metal to lose electrons and hence lower is the electropositive character of the metal.

- 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
- 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?
