Which reaction is not characteristic of an acid a)it dissolves magnesium oxide b) it produces ammonia from ammonium compounds c)it produces carbon dioxide from a carbonate d) it produces hydrogen from zinc metal

Acids are the substances that sour substances that have a pH ranging below 7. Acids do not produce ammonium compounds from ammonia. Thus, option b is correct.

What are acids?

Acids are the species that have been known to donate hydrogen or proton ions and even can accept electrons. The acids give their hydrogen or the proton to the metals in the aqueous solution and can produce hydrogen from zinc metal.

The acids can dissolve magnesium oxide to produce water along with magnesium chloride and even can release carbon dioxide from a carbonate along with water and calcium chloride. But they cannot produce ammonia instead they react with ammonia to yield ammonium ions.

Therefore, option b. acids cannot produce ammonia from ammonium compounds.
