Solution

The correct options are
C $H_{3} P O_{4}$
D $H_{3} P O_{2}$
Acids of non metal phosphorous react poorly with copper oxide.
$C u O + 2 H C l \to C u C l_{2} + H_{2} O$
$C u O + H_{2} S O_{4} \to C u S O_{4} + H_{2} O$
so, $H_{3} P O_{4}, H_{3} P O_{2}$ do not react with copper oxide.

Which acid will react poorly with copper oxide?

The correct options are C H3PO4 D H3PO2Acids of non metal phosphorous react poorly with copper oxide.CuO+2HCl→CuCl2+H2OCuO+H2SO4→CuSO4+H2Oso,H3PO4,H3PO2 do not react with copper oxide.

The correct options are
C $H_{3} P O_{4}$
D $H_{3} P O_{2}$
