In a redox reaction, which ion would you expect to be more easily reduced? In a redox reaction, which ion would you expect to be
Levart [38]

Answer:

In a redox reaction, hypochlorite ion would be more easily reduced.

Explanation:

Hypochlorite compounds are generally unstable - e.g. sodium hypochlorite is not available in solid form, because removing water from a NaClO disolution, causes a dismutation, turning it in a mixture of NaCl y NaClO3. Heating the same disolutions will also cause this effect. Hypochlorite will decompose under solar light into chlorides and oxygen.

Due to their low stability, hypochlorite compounds (i.e. those containing the hypochlorite ion) are very strong oxidants. Perchlorate ion can balance its negative charge instead and thus will be less prone to reduction than hypochlorite.
