What is H2O3 as a binary acid?

H2O3, also known as trihydric acid or hydrogen trioxide, is a hypothetical binary acid composed of hydrogen and oxygen. It is not commonly encountered in practice and is often considered an unstable or theoretical compound. In terms of acids, binary acids typically consist of hydrogen and one other element; H2O3 would not fit the conventional definitions used for common binary acids like HCl or H2S. Its properties and behavior as an acid are not well-documented due to its instability and rarity.
