Reducing property
Explanation:
\[\ce{CuO}\] functions as a reducing agent because it is reduced to \[\ce{Cu}\] (reddish brown ppt.) in the presence of ammonia.
\[\begin{array}{cc}
\ce{3CuO + 2NH3 ->3Cu + N2 + 3H2O}\\
\phantom{..}\ce{\underset{Reduction}{\underline{{\uparrow}\phantom{...................}{\uparrow}}}}\phantom{...............}
