Question

Species that increases the concentration of $H^{+}andO{H}^{-}ions$ in aqueous solution are called :

• A. Bronsted-Lowry acid and Bronsted-Lowry base
• B. Lewis acid and Lewis base
• C. Arrhenius acid and Arrhenius base
• D. All of the above.

Answer 1

The correct option is C Arrhenius acid and Arrhenius base

An Arrhenius acid is a compound that increases the H ⁺ ion concentration in aqueous solution.
An Arrhenius base is a compound that increases the OH ⁻ ion concentration in aqueous solution.
A Bronsted-Lowry acid is any species that can donate a proton to another molecule.
A Bronsted-Lowry base is any species that can accept a proton from another molecule.
A Lewis acid is a chemical species that contains an empty orbital which is capable of accepting an electron pair from a Lewis base.
A Lewis base is any substance, that can donate a pair of nonbonding electrons. A Lewis base is therefore an electron-pair donor.
