The definitions of acid and base based on the given concepts are:

1. Arrhenius (Svante Arrhenius):
- Acid: A substance that dissociates in water to produce H+ ions (protons).
- Base: A substance that dissociates in water to produce OH- ions (hydroxide).
2. Lux-Flood:
- Acid: A substance that accepts oxide ions (O²⁻).
- Base: A substance that donates oxide ions (O²⁻).
3. Usanovich (Ivan Usanovich):
- Acid: A substance that accepts an electron pair.
- Base: A substance that donates an electron pair.
4. Solvent System:
- Acid: A substance that donates a proton (H+) or accepts an electron pair in a solvent.
- Base: A substance that accepts a proton (H+) or donates an electron pair in a solvent.
5. Frontier Orbital (Molecular Orbital Theory):
- Acid: A substance with a low-energy empty molecular orbital (LUMO) that can accept electrons.
- Base: A substance with a high-energy filled molecular orbital (HOMO) that can donate electrons.

Note: These definitions are not mutually exclusive, and some concepts may overlap or complement each other.
