  1. Acid, any substance that in water solution tastes sour, changes the color of certain indicators (e.g., reddens blue litmus paper), reacts with some metals (e.g., iron) to liberate hydrogen, reacts with bases to form salts, and promotes certain chemical reactions (acid catalysis).

  2. Summary. Acidbase reactions always contain two conjugate acidbase pairs. Each acid and each base has an associated ionization constant that corresponds to its acid or base strength. Two species that differ by only a proton constitute a conjugate acidbase pair.

  3. Acids are molecular compounds that release hydrogen ions. A binary acid consists of hydrogen and one other element. Oxyacids contain hydrogen, oxygen, and one other element. The name of the acid is based on the anion attached to the hydrogen.

  4. Since acids produce \(\ce{H^+}\) cations upon dissolving in water, the \(\ce{H}\) of an acid is written first in the formula of an inorganic acid. The remainder of the acid (other than the \(\ce{H}\)) is the anion after the acid dissolves. Organic acids are also an important class of compounds, but will not be discussed here.

  6. 13 de ene. de 2020 · Updated on January 13, 2020. An acid is a chemical species that donates protons or hydrogen ions and/or accepts electrons. Most acids contain a hydrogen atom bonded that can release (dissociate) to yield a cation and an anion in water.

  7. 14 de feb. de 2023 · In chemistry, an acid is a chemical species that donates hydrogen ions or protons or accepts an electron pair. Acids react with bases and some metals via a neutralization reaction that forms a salt. They have a pH less than 7 and taste sour. The word acid comes from the Latin word acidus, which means “sour.”
