What are the products of the simplest type of acid-base reaction?

            Water and Salt are the products of simplest types of acid-base reactions.

Examples:

                           Base      Acid                 Salt           Water

                          NaOH  +  HCl       →      NaCl       +   H₂O

                       2 NaOH  +  H₂SO₄    →    Na₂SO₄  +  2 H₂O

                         NaOH    +  CH₃CO₂H  →   CH₃COONa  +  H₂O

In all theses simple reactions the base (i.e. OH⁻) abstracts proton from the acid and forming a conjugate base with negative charge. Thus the negative charged conjugate base forms a salt with positively charged sodium ions.

Afraidsugar lol it’s the third one

Ions gain or lose electrons
