However, even if we mix stoichiometrically equivalent quantities, we may find that the resulting solution is not neutral. In addition, a direct reaction between SO2 and SO3 gases with NaOH may be also be occurred to give a same products because those gases having acidic characteristics. It is basic because it contains the oxide ion, O 2-, which is a very strong base with a high tendency to combine with hydrogen ions.. As you move across the period, the oxides become more acidic. (Assume a solution is neutral if its pH is 7.00±0.05). They are called basic anhydrides. It will have a pH value close to zero. CaO + H2O → Ca(OH)2 Share this. Amphoteric –> Acidic. 1 decade ago.

It is basic because it contains the oxide ion, O 2-, which is a very strong base with a high tendency to combine with hydrogen ions. The lone electron pairs of the oxygen are donated to the sulfur. SO3- acidic oxide 3. Redox reactions commonly take place in acidic solutions. Specify whether the oxides BaO and SO3 are acidic, basic, or amphoteric. NH3 is a weak base with pH 11 ( at standard conditions) but it is also considered amphoteric which means it can act as both acid and base under different conditions. It could contain either an excess of hydronium ions or an excess of hydroxide ions because the nature of the salt formed determines whether the solution is acidic, neutral, or basic. $\endgroup$ – bon Feb 28 '16 at 10:16 $\begingroup$ A screenshot or picture of an exercise is not searchable. 1.
