### Basic Oxide Reaction with an Acid

For the reaction $MgO(s) + 2HCl(aq)\rightarrow MgCl_{2}(aq) + H_{2}O(l)$, the base $O^{2-}$ accepts two protons from the hydronium ions present in the hydrochloric acid solution. Is it assumed that all acidic solutions have $H_{3}O^{+}$ ions that can be used?

### Re: Basic Oxide Reaction with an Acid

I believe you can assume this because, by definition, if a solution is acidic, then it contains H3O+ ions. I think what we need to figure out is if the base (O2- in this case) is strong enough to break the H3O+ bond and accept the H+ ions to form a base.
