Partial precipitation of Mn^(2+) as Mn(O...

Partial precipitation of `Mn^(2+)` as `Mn(OH)_(2)` occurs with ammonia solution but the precipitate is soluble in ammonium salts. Explain?

Text Solution

Verified by Experts

`Mn^(2+)+2NH_(3)+2 H_(2)O hArr Mn(OH)_(2) darr ("white") +NH_(4)^(+)`
In presence of ammonium salts, the reaction proceeds in backward direction.
