1.

Ammonia is always added in this reaction. Which of the following must be incorrect?

Answer»

`NH_(3)` combines with `Ag^(+) ` to from a complex
`Ag((NH_(3))_(2)^(+)` is a weaker oxidizing reagent than `Ag^(+)`
In the ABSENCE of `NH_(3)` silver SALT of gluconic acid is formed electrode

SOLUTION :`NH_3` has no effect on the standard REDUCTION potential.
. The potential difference developed between metal electrode and the solution of its ions of unity molarity ( 1 M) at `25^(@)` C is called standard electrode potential.
. The standard reduction potential of an electrode means that reduction reaction is taking PLACE at the electrode.
