Feb 14, 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.”
Acids react with bases to produce a salt compound and water. When equal moles of an acid and a base are combined, the acid is neutralized by the base. The products of this reaction are an ionic compound, which is labeled as a salt, and water.
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).

Acids and bases can be described using the Arrhenius model: acids produce H+ ions in aqueous solutions, while bases produce OH- ions. We can identify acidic and basic solutions using their distinct and often contrasting properties, some of which you are likely familiar with!

Apr 28, 2021 · 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.
Jan 13, 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.
An acid is a substance that forms hydrogen ions H + when dissolved in water, and A base is a substance that forms hydroxide ions OH - when dissolved in water. For example, hydrochloric acid (\(\ce{HCl}\)) is an acid because it forms \(\ce{H^{+}}\) when it dissolves in water.
