Which of the following substances is the most powerful oxidizing agent? br2 ci2 cr3+ sn2+

CI2

Explanation:

An oxidising agent is one which oxidises other elements and gets reduced in the process. In other words, it has a greater tendency to accept electrons.

The oxidising ability of an element can be estimated based on its standard reduction potential (E⁰). More positive the reduction potential of an element, greater will be its ability to accept electrons are behave as a powerful oxidising agent.

In the given examples, the E⁰ for Cl2 is the most positive at 1.36 V i.e.

Cl2 + 2e- → 2Cl-          E⁰ = +1.36 V

Hence, Cl2 will be most powerful oxidising agent

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
