WebIn the more general Brønsted–Lowry acid–base theory (1923), a base is a substance that can accept hydrogen cations (H + )—otherwise known as protons. This does include aqueous hydroxides since OH − does react with H + to form water, so that Arrhenius bases are a subset of Brønsted bases.
WebAccumulation of formic acid can cause an anion-gap acid-base imbalance. If formalin is ingested, absorption of the methanol stabilizer may contribute to the imbalance and can result in an osmolal gap, as well as an anion gap. Immunologic.

In the Brønsted–Lowry model you cannot have an acid without a base, and vice versa; the acid has to donate its H+ to something (the base), and similarly the base has to accept it. The H + doesn’t just “drop off”—it is transferred.
