What is the total number of moles (n) of electrons exchanged between the oxidizing agent and the reducing agent in the overall r

Sergeu [11.5K]

Answer:
5 moles of electrons

Explanation:

The balance equation is as follow,

<span> 5 Ag</span>⁺ + Mn⁺²<span> + 4 H</span>₂O →<span> 5 Ag + MnO</span>₄⁻<span> + 8 H</span>⁺

Reduction of Ag:

Ag⁺ + 1 e⁻ → Ag
Or,
5 Ag⁺ + 5 e⁻ → 5 Ag

Oxidation of Mn:

Mn⁺² → MnO₄⁻ + 5 e⁻

Result:
Hence 5 moles of Ag⁺ accepts 5 electrons from 1 mole of Mn⁺².

Write the chemical formula for the cation present in the aqueous solution of cuso4.

Inessa05 [86]

The ionic compounds on dissolving in aqueous solution dissociate into their respective ions that are cations and anions.

The ions present in the aqueous solution of $CuSO_4$ are $Cu^{2+}$ and $SO_{4}^{2-}$ .

So, the chemical formula of the cation present in the aqueous solution of $CuSO_4$ is $Cu^{2+}$ .
