Answer:

Acids are characterized by the presence of #H^+# ions in the solution.
According to Arrhenius concept of acids and bases acids ionize in water to give #H^+# ions in solution. Example:

Explanation:

#HNO_3# #rightleftharpoons# #H^+# + #NO_3^-#
#H_2SO_4# #rightleftharpoons# #2H^+# + #SO_4^-2#
#HI# #rightleftharpoons# #H^+# +#I^-#
You can see that all of the above are acids which ionize in solution to give #H^+# ions .
