There's basically 3 different definitions for acids and bases...since noone can really decide what they are. They're all correct and often overlap.
Standard definition ([H+] rise/[OH-] rise)
Lewis definition (Lone pair acceptor/donor)
Bronsted-Lowry definition (H acceptor/donor)
The Lewis theory says that acids are lone pair acceptors and bases are lone pair donors.
So if we say something "acts like a Lewis acid" it means it's accepting a lone pair (of electrons, that is!) in that reaction. It's a great way of describing a molecule's role in the reaction just by referring to it.
It's worth mentioning that if we have the reaction:
A + B ---> C + D
If A is a Lewis acid, then B must be a Lewis base. (If A is accepting a pair of electrons...it's gotta get them from somewhere and B is the only other thing there, so B must be a lone pair donor).
As a final note, it's important to remember that here no molecule is always an acid or always a base. The words acid and base simply describe how that molecule acts in the reaction...it's the role it plays rather than a permanent property of the molecule itself.
If you're unsure what a lone pair is, now is the time forget acids and bases and take a moment to learn that first.

What are the three Acid Base Theories?
The three acid-base theories are the Arrhenius theory, which defines acids as substances that release hydrogen ions in solution and bases as substances that release hydroxide ions in solution; the Brønsted-Lowry theory, which defines acids as proton donors and bases as proton acceptors; and the Lewis theory, which defines acids as electron pair acceptors and bases as electron pair donors.
What are the 3 acid and base theories?
The three acid-base theories are the Arrhenius theory, which defines acids as substances that release protons in solution and bases as substances that release hydroxide ions; the Brønsted-Lowry theory, which defines acids as proton donors and bases as proton acceptors; and the Lewis theory, which defines acids as electron pair acceptors and bases as electron pair donors.
Why statement describes an alternate theory of acids and bases?
The Why statement is a theory that suggests acids and bases react as a result of the difference in electronegativity between hydrogen and oxygen. In this theory, acids donate protons due to the electronegativity difference between hydrogen and oxygen, while bases accept protons. This theory provides an explanation for the behavior of acids and bases in terms of electron movement.
What theory of acids and bases do conjugate acids and bases belong to?
Conjugate acids and bases belong to the Bronsted-Lowry theory of acids and bases. In this theory, an acid donates a proton (H+) and a base accepts a proton. A conjugate acid is formed when a base accepts a proton, and a conjugate base is formed when an acid donates a proton.
How does Lewis define acids and bases?
Lewis defined acids as substances that are electron pair acceptors, and bases as substances that are electron pair donors. According to Lewis, acids and bases react by sharing an electron pair to form coordinate covalent bonds.
What is the difference between the bronsted-lowry theory and the theory of acids and bases propose by newton Lewis?
The Brønsted-Lowry theory defines acids as proton donors and bases as proton acceptors, focusing on the transfer of hydrogen ions (H⁺) in chemical reactions. In contrast, the Lewis theory broadens the definition of acids and bases by describing Lewis acids as electron pair acceptors and Lewis bases as electron pair donors, emphasizing electron interactions rather than just proton transfer. This distinction allows the Lewis theory to encompass a wider range of chemical reactions beyond those involving protons. Thus, while Brønsted-Lowry is more specific to proton transfer, Lewis theory addresses broader electron pair dynamics.

Why do you think bases are often described the opposite of acids?
1) Bronsted-Lowry acids are proton donors. Bronsted-Lowry bases are proton acceptors. 2) Lewis acids are electron acceptors. Lewis bases are electron donors.

Conjugate acids and bases belong to the Bronsted-Lowry theory of acids and bases. In this theory, an acid donates a proton (H+) and a base accepts a proton. A conjugate acid is formed when a base accepts a proton, and a conjugate base is formed when an acid donates a proton.
Why do you think bases are often described as the opposite of?
1) Bronsted-Lowry acids are proton donors. Bronsted-Lowry bases are proton acceptors. 2) Lewis acids are electron acceptors. Lewis bases are electron donors.

What is the Bronsted-Lowry theory and how does it define the relationship between acids and bases?
The Brnsted-Lowry theory defines acids as substances that donate protons (H ions) and bases as substances that accept protons. According to this theory, an acid-base reaction involves the transfer of a proton from the acid to the base. This theory expands the definition of acids and bases beyond the traditional concept of acids as substances that release hydrogen ions and bases as substances that release hydroxide ions.
What is the definition of Lewis Acids and Bases?
A Lewis acid is therefore any substance, such as the H+ ion, that can accept a pair of nonbonding electrons. In other words, a Lewis acid is an electron-pair acceptor. A Lewis base is any substance, such as the OH- ion, that can donate a pair of nonbonding electrons. A Lewis base is therefore an electron-pair donor.
