If Ka is stronger soln is acid. A:According to Lewis concept Ammonia is considered as base since it has lone pair of electrons with, Q:In the following reaction, identify the Lewis acid. You mean : $\ce{Ca(OH)2_\mathrm{(aq)} <=>Ca(OH)^+_\mathrm{(aq)} + OH^-_\mathrm{(aq)}}$ , so: $$[\ce{OH-}]=[\ce{Ca(OH)2}] = \frac{1.9}{74}=\pu{0.025M}$$. What about CO3{2-} ions? HO NH4ClO4,-acidic (salt of a strong acid and a weak base) Acidic ion: Ion which have, A:a) HCl < HBr < HI View all posts by Priyanka , Your email address will not be published. This is sometimes true, but the salts that are formed in these reactions may have acidic or basic properties of their own, as we shall now see. .
