acid and basic radical of (NH4)2SO4
Answers
Answer:
Explanation:
NH4 is a positively charged ion. It is also the conjugate acid to ammonia (it is the protonated form of ammonia). Ammonia is basic and its conjugate acid is acidic. Ammonia is a weak base.
Sulfate is a negatively charged ion. It is the conjugate base (proton removed) to HSO3, which is the conjugate base to H2SO4, sulfuric acid. Sulfuric acid is a really strong acid.
Usually, when you mix an acid and a base, you get a salt and water (H from acid + OH from base -> H2O). (The exception is with Lewis acids and bases, but I won't go into that here.) If you mix a strong acid and a weak base, the salt will be acidic. If you mix a strong base and a weak acid, the salt will be basic. If you mix a strong base and a strong acid, the salt will be neutral (sodium hydroxide plus hydrochloric acid gives water and sodium chloride, table salt, which is neutral).
In this case, you have the resulting salt from the mixture of a weak base and a strong acid. Thus it could plausibly be acidic*. At least this agrees with what other people reported from wikipedia.
*One thing that makes it more complicated though is the fact that it is harder to remove a second proton from sulfuric acid than it is to remove the first one. Without knowing pKa values explicitly, I can't make clear predictions.
(NH 4)2 is basic Racidal while SO4 is acidic i give the direct answers without any fuzzy talking
