First, a basic salt will typically be colorless or white in appearance. Give an example of such an oxide. It's just a hydrogen-bonded complex that happens to retain some semblance of existence in the solid. To think about a different example acetic acid is a weaker acid, $\text{pK}_\text{a} = 4.76$, so the acetate anion is a stronger base than the sulfate anion. [H+]=7.22106M c. [H+]=8.05107Md. HS. a.
