Answer:

Oxides that form neither an acid nor a base, in combination with water.

Explanation:

Acid oxides will react with water to ultimately give off #H^+#:
Sulphur trioxide #SO_3# will form sulfuric acid:
#SO_3 (g) + H_2O (l)->H_2SO_4# which will give off #H^+#

Basic oxides will accept #H^+#:
Calcium oxide #CaO# will form a base:
#CaO (s)+H_2O(l)->Ca(OH)_2#
The #OH^-# part combining with #H^+# to form water.
Ferrous oxide #FeO# will not combine with water, but it will accept #H^+# from an acid:
#FeO+2H^+ ->Fe^(2+)+H_2O#

Neutral oxides do neither. Examples are carbon monoxide (#CO#), nitrogen monoxide (#NO#), and of course water (#H_2O#)
