Calculate the number of moles of Sn^(2+)ion oxidise by 1 mole of K_(2)Cr_(2)O_7in acidic medium.

Calculate the number of moles of Sn^(2+)ion oxidise by 1 mole of K_(2)

1.	Calculate the number of moles of Sn^(2+)ion oxidise by 1 mole of K_(2)Cr_(2)O_7in acidic medium.
Answer» Solution : `[Sn^(2+) RARR Sn^(4+) +2e^(-)]xx3` `:.` 1 MOL of`K_(2)Cr_(2)O_7`will oxidise 3 mole of `Sn^(2+)`
