Brønsted-Lowry concept
Brønsted-Lowry acids are substances that can donate a proton (H+) to another substance; Brønsted-Lowry bases are substances that can accept a proton (H+).
A substance with transferable protons is an acid, such as HNO₂ in this example:
A substance that can receive a transferable proton is a base, such as water in this example:
Part B
One benefit of the Brønsted-Lowry concept of acids and bases is that it is not limited to aqueous solutions and can be applied to gases, liquids, and solids.
Drag the appropriate items to their respective bins.

Definitions of Acids and Bases
Arrhenius concept
Arrhenius acids are substances that, when dissolved in water, increase the concentration of the H+ ion; Arrhenius bases are substances that, when dissolved in water, increase the concentration of the OH ion.
For example, a substance with an ionizable protons is an acid:
A substance that can either directly or indirectly increase hydroxide ions is a base:
NH3(aq) + H₂O(1) NH4+ (aq) + OH (aq)
However, the Arrhenius concept only applies aqueous solution. It does not apply to reactions in other phases, which ultimately lead to the use of other definitions for such systems.
