Question

How many covalent and coordinate bonds are present in hydronium ion and ammonium ion?

Answer 1

Answer:

It is formed from a hydrogen ion and water bonding. Hydronium contains 2 polar covalent bonds and 1 coordinate covalent bond. So by definition, there are three covalent N-H bonds and one N → H coordinate bond in NH4+ ion.

Answer 2

Answer:

Ammonium ions can be identified in a solution by adding dilute sodium hydroxide solution and gently heating. If ammonium ions are present, they will be converted to ammonia gas. Ammonia has a characteristic choking smell. It also turns damp red litmus paper or damp universal indicator paper blue.
