you can treat them with
#tollen reagent
#fehling solution

acetaldehyde shows action on these and acetone don't react

Answer 2

$\huge\textcolor{green}{\texttt{Answer :-}}$

Acetaldehyde gives red percipitate(ppt) on heating with Fehling's solution whereas acetone does not.

$CH_3CHO + 2CuO(present\: in\: Fehling's\: solution) ---)$

$CH_3COOH + Cu_2O(red \:ppt)$

NOTE : This reaction takes place under the presence of heat energy.
