Select all that apply. which of the following are characteristics of acids? contain hydroxide ion or produce it in a solution taste sour corrode metals produce hydronium ion in a solution

These are the characteristics that apply:

 - In a solution taste sour: which is consequence of the H+ concentration.

- Corrode metals: the H+ ion reacts with the metal producing a salt and water

-Produce hydronium ion in solution: as per the Bronsted - Lowry definition an acid is a substance that donates a proton, H+. This proton will react with H2O to form H3O+ (hydronium), as per this scheme: 

HA + H2O --> A(-) + H3O(+)
