#"An acid.............."#

Explanation:

In aqueous solution, any species that increases the concentration of the characteristic cation #H^+# or #H_3O^+# is called an acid. The actual acidium species is likely a cluster of water molecules with an EXTRA #H^+#, i.e. #H_3O^+# or #H_5O_2^+#. It is convenient and chemically transparent to represent it is as #H^+# or #H_3O^+#. The #H^+# is conceived to be able to tunnel from cluster of water molecules to cluster.
