Tollen's test is given by aldehydes:
`Ag^(+)+barerarrAg, E_(red)^@=+0.800V` and `C_6H_12O_6+H_2OrarrC_6H_12O_7+2H^=+2bare, E_(ox)^@=-0.05V`
`[Ag(NH_3)_2]+barerarrAg+2NH_3, E_(red)^@=+0.373V` use `(F)/(RT)=38.9 V^-1`
`NH_4` is used in this reaction rather than any other base, what is the correct reason for this?

A

`Ag(NH_3)_2]^+` is a weaker oxidising agent than `Ag^+`.

B

`NH_3` prevents the decomposition of glucnic acid.

C

Ag precipitated gluconic acid as a silver salt.

D

`NH_3` changes the standard reduction potenital of `[Ag(NH_3)_2]`.
