The stoichiometry of the balanced chemical equation depends on the number of H + ions in the acid and the number of OH − ions in the base. A reaction between an acid and a base is called a neutralization reaction and can be represented as follows: A salt, in chemistry, is any ionic compound made by combining an acid with a base. They are slippery to the touch, turn litmus blue, and have a bitter flavour if ingested.Īcids and bases have another property: they react with each other to make water and an ionic compound called a salt. (The name acid comes from the Latin word acidus, meaning “sour.”) Bases also have some properties in common. Acids that are ingested typically have a sour, sharp taste. They react with carbonate and hydrogen carbonate salts to give off CO 2 gas. They react with some metals to give off H 2 gas. As such, this is an ionic compound of the OH − ion and is an Arrhenius base.Īcids have some properties in common. This formula also has an OH in it, but this time we recognize that the magnesium is present as Mg 2+ cations.(In fact, it is the formula for methanol, an organic compound.) Although this formula has an OH in it, we do not recognize the remaining part of the molecule as a cation.This compound is an ionic compound between H + ions and NO 3 − ions, so it is an Arrhenius acid.Identify each compound as an Arrhenius acid, an Arrhenius base, or neither. Ionic compounds of the OH − ion are classic Arrhenius bases. Table 12.2 Some Arrhenius Acids FormulaĪn Arrhenius base is a compound that increases the OH − ion concentration in aqueous solution. Table 12.2 “Some Arrhenius Acids” lists some Arrhenius acids and their names. Classic Arrhenius acids can be considered ionic compounds in which H + is the cation. H + ions and H 3O + ions are often considered interchangeable when writing chemical equations (although a properly balanced chemical equation should also include the additional H 2O). Instead, chemistry has defined the hydronium ion (H 3O +) as the actual chemical species that represents an H + ion. The H + ion is just a bare proton, and it is rather clear that bare protons are not floating around in an aqueous solution. An Arrhenius acid is a compound that increases the H + ion concentration in aqueous solution. Historically, the first chemical definition of an acid and a base was put forward by Svante Arrhenius, a Swedish chemist, in 1884.
