Among the following strongest oxidising agent is:a)[WO4]2-b)[CrO4]2-c)...
Explanation:
To determine the strongest oxidizing agent among the options given, we need to consider the reduction potential of each species. The higher the reduction potential, the stronger the oxidizing agent.

Reduction Potentials:
1. [WO4]2-: Tungsten(VI) has a reduction potential of +0.91 V.
2. [CrO4]2-: Chromium(VI) has a reduction potential of +1.33 V.
3. [MoO4]2-: Molybdenum(VI) has a reduction potential of +0.74 V.
4. [ReO4]2-: Rhenium(VII) has a reduction potential of +0.87 V.

Analysis:
The species with the highest reduction potential is [CrO4]2- (+1.33 V). Therefore, it is the strongest oxidizing agent among the options given.

Conclusion:
The correct answer is option 'B' [CrO4]2- as it has the highest reduction potential, indicating that it is the strongest oxidizing agent.
