Arrhenius theory (1887) the theory stating that acids and bases are defined in terms of their structure and the ions produced when they dissolve in water defines an acid as a substance that produces hydrogen ions in water and a base as a substance that produces hydroxide ions in water (8.1) asymmetrical alkene an alkene that has different groups on either side of the double bond (2.2) atom the basic unit of an element, which still retains the element s properties (Review)... 

According to the Arrhenius definition of acids and bases, acids are substances that produce hydrogen ions (H+) in solution, and bases are substances that produce hydroxide ions (OH ) in solution. When an acid and a base combine, the hydrogen ions from the acid react with the hydroxide ions from the base to form water—a neutralization reaction. 

Pure water can be considered both an acid and a base because water dissociates slightly to produce hydrogen and hydroxide ions H2Offi < > H+(a(i) + OH (a. This equation depicts water as an Arrhenius acid and base. An Arrhenius acid is any substance which when dissolved in water produces hydrogen ions, H+. An Arrhenius base is a substance that produces hydroxide ions, OH. Treating water in terms of the Brans ted-Lowry theory, a more appropri-...

An add can be defined as a substance that produces hydrogen ions, H, in aqueous solutions. We usually write the formulas of inorganic acids with hydrogen written first. Organic acids can often be recognized by the presence of the COOH group in the formula. A base is a substance that produces hydroxide ions, OH , in aqueous solutions. A salt is a compound that contains a cation other than H and an anion other than hydroxide ion, OH , or oxide ion, (see Table 2-3 on page 55). As we will see later in this chapter, salts are formed when acids react with bases. 

The behavior of bases is also described at the molecular level by the interaction of the base with water. A base is a substance that produces hydroxide ions, OH, when it dissolves in water. There are two mechanisms by which bases produce hydroxide ions when they dissolve in water. 

According to the modern version of the Arrhenius theory of acids and bases, a base is a substance that produces hydroxide ions, OH , when it is added to water. A solution that has a significant concentration of hydroxide ions is called a basic solution. Sodium hydroxide, NaOH, is the most common laboratory base. It is designated a strong base because for every NaOH unit dissolved, one hydroxide ion is formed in solution. 

Weak base A substance that produces fewer hydroxide ions in water solution than particles of the substance added. 

Arrhenius also found that aqueous solutions that exhibit basic behavior always contain hydroxide ions. He defined a base as a substance that produces hydroxide ions (OH ) in water. The base most commonly used in the chemical laboratory is sodium hydroxide, NaOH, which contains Na and OH ions and is very soluble in water. Sodium hydroxide, like all ionic substances, produces separated cations and anions when it is dissolved in water. 

A base is a substance that produces hydroxide ion and/or accepts H+. Many bases consist of metal ions and hydroxide ions. For example, solid sodium hydroxide dissolves in water to yield a solution containing OH ions ... 

An Arrhenius base is a substance that produces hydroxide ions, OH, when it dissolves in water. For example, sodium hydroxide is a base.

Svante Arrhenius (1859-1927) was a Swedish physical chemist who was awarded the Nobel Prize in Chemistry in 1903 for his work on ionic solutions. His theory of acids and bases defined acids as substances that produce hydrogen ions in solution (as the only positive ions) and bases as substances that produce hydroxide ions (as the only negative ions). In addition he explored the relationship between the rate of a chemical reaction and temperature. The equation which bears his name was originally proposed by the Dutch chemist J.H. varit Hoff, but it was Arrhenius who provided a physical interpretation and justification for it When the temperature increases, the rate of a chemical reaction increases very rapidly. It has been found that for many reactions, the initial rate and the rate constant. 

From a practical standpoint, we can identify bases through their bitter taste, slippery feel, and effect on the colors of acid-base indicators (Fig. 5-9). The Arrhenius definition of a base is a substance that produces hydroxide ions (OFf ) in aqueous solution. Consider a soluble ionic hydroxide, such as NaOFl. In the solid state, this compound consists of Na" " and OFf ions. When the solid dissolves in water, the ions dissociate. 

According to Arrhenius s definition, an acid is a substance that produces hydronium ion (H3O ), and a base produces hydroxide ion (OH ) in aqueous solution. An acid reacts with a base to produce salt and water. 

A substance that produces hydroxyl ions, OH, when dissolved in water. An alkali is a soluble base. A base is usually an oxide or hydroxide of a metal. 

According to the Arrhenius concept, a base is a substance that produces OH-ions in aqueous solution. According to the Bronsted-Lowry definition, a base is a proton acceptor. The bases sodium hydroxide (NaOH) and potassium hydroxide (KOH) fulfill both criteria. They contain OH- ions in the solid lattice and behave as strong electrolytes, dissociating completely when dissolving in water ... 

Answer An acid is any substance that produces hydronium ion, H30+, when dissolved in water. A base is any substance that produces hydroxide ion, OH", when dissolved in water, and neutralization is the reaction between an acid and base to produce water. 

Bases are considered the chemical opposite of acids because of their ability to neutralize acids. In 1887 the Swedish physicist and chemist Svante Arrhenius defined a base as the chemical substance that produces hydroxide ions (OH ) and cations. A typical base, according to the Arrhenius definition, is sodium hydroxide (NaOH). The neutralization of an acid with a base to yield salt and water may be represented as... 

In the Arrhenius definition, an acid is a substance that produces hydrogen ions (H ) when dissolved in water. An Arrhenius base produces hydroxide ions (OH ) when dissolved in water. These definitions are not complete because they limit the bases to compoimds with a hydroxide ion, and the only allowable solvent is water. 

A base is a substance that contains hydroxide ion OH , or produces it when dissolved in water. Most of the best-known inorganic bases have a formula unit composed of a metal cation and 1 or more hydroxide ions. Typical of these are sodium hydroxide, NaOH, and calcium hydroxide, Ca(OH)2, which dissolve in water to yield hydroxide ion and their respective metal ions. Other bases, such as ammonia, NH3, do not contain hydroxide ion, but react with water. 

Acids are substances that produce H+ ion in water solution and bases are substances that produce OH ion. Salts are substances that are composed of ions and that contain a cation other than H+ and an anion other than OH . Salts can be produced by the reaction between H+ ion from an acid and OH ion from a base, a neutralization reaction. As a specific example, consider the reaction of H+ from a solution of sulfuric acid, H2SO4, with OH" from a solution of calcium hydroxide ...
