To classify a substance as an Arrhenius acid or base, or as a Brønsted-Lowry acid or base, you must consider how the substance b
aleksandr82 [10.1K]

Answer:

Ammonia is an Arrhenius base and a Brønsted-Lowry base.

Explanation:

An Arrhenius base is any substance which, when it is dissolved in an aqueous solution, produces hydroxide (OH^-), ions in solution. An aqueous solution is a solution that has water present in it.

A Bronsted-Lowry base is a substance that accepts a proton, that is, a hydrogen ion (H^+).

Looking at the equation above, ammonia satisfies both characteristics. We can see that when ammonia is dissolved in water, hydroxide ions is produced in the solution. Hence it is an Arrhenius base. Similarly, the hydroxide ion is formed when ammonia accepts a proton. This is a characteristic of a Brownstead-Lowry base. Hence ammonia is both an Arrhenius base and a Brownstead-Lowry base.

In which of the three acid-base concepts can water be a product of an acid-base reaction? In which is it the only product?
Archy [21]

Salt and water is formed as product, when Arrhenius acid and Arrhenius base reacts and the reaction is known as neutralization reaction.

<h3>What is Arrhenius acid-base reaction?</h3>
  • The concept of acid and base based on the theory of ionization which was first proposed in 1884 by Svante Arrhenius
  • According to Arrhenius, on dissociation in water the hydrogen-containing compounds which give H+ ions or protons are the acids and  the hydroxide compounds which give OH− ions on dissociation in water are bases.
  • This theory is applicable only to compounds which are dissolved in aqueous solution.

Neon has 8 electrons in it's outer shell. Does it need to bond? Why or why not?
Lena [83]
No.!!
As it has full filled valence electrons, they can't form bonds, due to lack of vacant electrons.

Hope this helps!
