Answer:

See explanation.

Explanation:

According to the Bronsted definition:

  • Acid: is an #H^+# donor.
  • Base: is an #H^+# acceptor.

Example:
Bronsted Acid: #HCl->H^++Cl^-#
Bronsted Base: #NH_3+H^(+)->NH_4^+#

According to the Lewis definition:

  • Acid: is an electron lone pair acceptor.
  • Base: is an electron lone pair donor.

Example:
Lewis Acid: #AlCl_3#
Lewis Base: #H_2O#
