Does formaldehyde give silver mirror test

Answer 1

YessssssssssssssYes

Answer 2

ANSWER:

Yes, formaldehyde give silver mirror test.

EXPLANATION:

Silver mirror test is the tollen’s reagent.  It is the ammonical solution of 'Silver Nitrate'.

Its chemical formula is $\bold{\left[A g\left(\mathrm{N} H_{3}\right)_{2}\right] O H}.$ Tollen’s reagent is prepared by adding 'Ammonium Hydroxide' $\bold{\left(N H_{4} O H}\right)$ to 'Silver Nitrate solution' $\bold{A g N O_{3}}$

Black precipitates of $\bold{\mathrm{AgOH}}$ are dissolved in excess of $\bold{\mathrm{NH}_{4} \mathrm{OH}}$ to produce a molecule known as tollen’s reagent.

When Methanol or formaldehyde is heated with tollen’s reagent, "bright silver mirror" is produced on the inner side of the test tube.

$\bold{H-C H O+2\left[A g\left(N H_{3}\right)_{2}\right] O H \rightarrow H-C O O H+2 A g+H_{2} O+4 N H_{3}}$
