@argentum There is a definition: acids are called hydroxides, which, when interacting with bases, form salts. Nitric acid in an aqueous solution is neutralized, as is carbonic acid with one mole of alkali. In this case, acidic salts are formed - acidic hyponitrites MeH(N2O2) and medium salts - hyponitrites Me2(N2O2). Judging by the definition, nitric acid is a hydroxide. It seems to me that this is a fair statement and has a place to be.
@damiryagudin To be honest, apparently a narrow definition, I did not find this in the textbooks. In addition, as I said, this definition is misleading, mixing different classes of compounds, leading to a stupor
@nanochimik47 Judging by the different definitions, there may be some degree of confusion here. In your opinion, how would you define the term acid?
@nknh716 A compound capable of exchanging hydrogen atoms or ions for metal cations
