Sing the brønsted-lowry concept of acids and bases, identify the brønsted-lowry acid and base in each of the following reactions: hso3−(aq)+h2o(l)→h2so3(aq)+oh−(aq) (ch3)3n(g)+bcl3(g)→(ch3)3nbcl3(s)

a) : Bronsted base

: Bronsted acid

b) None

Explanation:

According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.

For the given chemical equations:

a)

Here, is accepting a proton, thus it is considered as a base and after gaining a proton, it forms which is an conjugate acid.

And, is losing a proton, thus it is considered as a acid and after losing a proton, it forms which is a conjugate base.

b) [tex[(CH_3)_3N(g)+BCl_3(g)\rightarrow (CH_3)_3NBCl_3(s)[/tex]

As there is no donation or acceptance of , they cannot be considered as Bronsted acid or base. gives its electrons to , thus act as lewis base and act as lewis acid.
