When dissolved in water, acids produce hydrogen ions oxide ions polyatomic ions negative ions?

When dissolved in water, acids produce .

Further explanation:

Different theories have definitions of acids and bases. These theories are as follows:

1. Arrhenius theory: According to this theory, acid produces hydrogen or hydronium ions in a solution, while the base produces hydroxide ions in a solution. HCl,  and   are Arrhenius acids while NaOH and KOH are the examples of Arrhenius bases.

2. Bronsted-Lowry theory: This theory defines acid as the proton donor and base as the proton acceptor.  acts as Bronsted acid while  is a Bronsted base.

3. Lewis theory: According to this theory, an acid accepts a pair of electrons to electron-rich species while a base donates electrons to electron-deficient species in the reaction. Examples of Lewis acids are ,  while  and ROH are the examples of Lewis base.

According to Arrhenius's theory, acid is the substance that dissociates in water to produce hydrogen ions. So hydrogen ions are produced by acids when these are dissolved in water.

The dissociation of HCl in water occurs as follows:

HCl produces  ions in water and therefore it is an acid.
