the Bronsted-Lowry theory classifies a substance as an acid if it acts as a proton(H+) donor, and as a base if it acts as a proton acceptor.
The theory that describes an acid as a proton donor and a base as a proton acceptor is the Brønsted-Lowry acid-base theory. In this theory, an acid is defined as a species that donates a proton (H+), while a base is a species that accepts a proton. This theory is widely used in understanding and predicting acid-base reactions.
Hydrogen can be both an acid and a base depending on the context. In the Brønsted-Lowry theory, it can act as an acid by donating a proton (H+) or as a base by accepting a proton. In the Lewis theory, hydrogen can act as a base by donating a pair of electrons.
Phosphate ion (PO4 3-) acts as a base in the Bronsted-Lowry acid-base theory by accepting a proton (H+).
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.
The Brønsted-Lowry theory defines an acid as a substance that donates a proton (hydrogen ion) in a chemical reaction, while a base is a substance that accepts a proton. This theory focuses on proton transfer between substances in a reaction to explain acid-base behavior.

Theory of everything
Hydrogen can be both an acid and a base depending on the context. In the Brønsted-Lowry theory, it can act as an acid by donating a proton (H+) or as a base by accepting a proton. In the Lewis theory, hydrogen can act as a base by donating a pair of electrons.
The currently accepted theory is the Lewis acid-base theory A Lewis base is an electron donor and a Lewis acid is a electron acceptor. Whether a compound is acid or base may not be obvious at first and difficult to work out. There are rules for working this out but you probably dont have to know them Generally, all you would probably have to know is that an acid is a proton [H+] donor and a base is proton acceptor

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.
acid: electron pair acceptor Base: electron pair donor
The Brønsted-Lowry theory defines an acid as a substance that donates a proton (hydrogen ion) in a chemical reaction, while a base is a substance that accepts a proton. This theory focuses on proton transfer between substances in a reaction to explain acid-base behavior.
The Brønsted-Lowry acid-base theory was devised in 1923 by two independent people. Jahannes Brønsted and Thomas Lowry. In this theory an acid base reaction is one that involves the transfer of a hydrogen ion (H+) from one substance to another. The acid donates the ion while the bases accepts it.ExampleHCl + H2O → H3O+ + Cl- Hydrochloric acid (HCl) is an acid because it donated a proton (hydrogen) to the water creating a hydronium ion.NH3 + H2O → NH4+ + OH-Ammonia (NH3) is a base because it accepts a proton from the water molecule to form ammonium.
Lithium Oxide is a base because when it is added to an acid for example Hydrochloric Acid (HCL) it is neutralised. Acid + Base is a neutralisation reaction. + Plus look at Arhenius's explanation on the theory of acid reactions and Bronsted lowry's theory on acids and bases. Because somewhere in there they talk about somthing that might help you a bit more if you are not confident with my answer.
The simplest type of acid-base reaction can be represented by the general equation: [ \text{HA} + \text{B} \rightarrow \text{A}^- + \text{HB}^+ ] In this equation, HA represents an acid that donates a proton (H⁺) to the base B, resulting in the formation of its conjugate base A⁻ and the conjugate acid HB⁺. This transfer of protons is the hallmark of Brønsted-Lowry acid-base theory.
The factors considered in the Bronsted-Lowry theory for acids and bases are the proton (H+) and the hydroxyl anion (OH-). An acid is considered something that donates or generates H+ and a base is considered something that donates or generates OH-
