Statement 1: Formic acid reduces 'Tollens reagent'.
Statement 2: Compounds containing `(-CHO)` group reduce 'Tollens reagent'.

Explanation

HCOOH has an aldehydic (CHO) group in addition to carboxyl group (COOH). Therefore, it is expected to behave as reducing agent also and reduces Tollen's reagent to form a shining mirror.
