Which two of the following oxides would NOT give acidic solutions in water?
CO, CO_2, SO_2, NO
A. NO and SO_2
B. NO and CO_2
C. CO and SO_2
D. CO and CO_2
E. CO and NO

A. NO and SO_2
B. NO and CO_2
C. CO and SO_2
D. CO and CO_2
E. CO and NO
CO (g) + H_2O (l) → CO_2 (g) + H_2 (g)
This is not an acidic solution in water.
CO_2 + H_2O → H_2CO_3
This produces carbonic acid and is so obviously an acidic solution in water.
SO_2 (aq) + H_2O (l) → H_2SO_4 (aq)
This produces sulphuric acid, which is also an acidic solution in water.
4 NO (g) + 6 H_2O (l) → 5 O_2 (g) + 4 NH_3 (aq)
This is not an acidic solution in water.
Therefore the answer is NO and CO, option E.
