Aqueous Arrhenius acids have characteristic properties which provide a practical description of an acid. Chemicals or substances having the property of an acid are said to be acidic. Common aqueous acids include hydrochloric acid a solution of hydrogen chloride which is found in gastric acid in the stomach and activates digestive enzymes , acetic acid vinegar is a dilute aqueous solution of this liquid , sulfuric acid used in car batteries , and citric acid found in citrus fruits. As these examples show, acids in the colloquial sense can be solutions or pure substances, and can be derived from acids in the strict [1] sense that are solids, liquids, or gases.

Overview of Acids and Bases

An acid—base reaction is a chemical reaction that occurs between an acid and a base. It can be used to determine pH. Their importance becomes apparent in analyzing acid—base reactions for gaseous or liquid species, or when acid or base character may be somewhat less apparent. The first of these concepts was provided by the French chemist Antoine Lavoisier , around It is important to think of the acid-base reaction models as theories that complement each other. The first scientific concept of acids and bases was provided by Lavoisier in around

At last we have arrived at the place where many chemistry courses begin: chemical reactions. In this chapter we will examine what a chemical reaction is, which processes are not chemical reactions, how chemical reactions occur, and how they are characterized. We will also look at how molecules come to be reorganized during a chemical reaction. In Chapter 8, we will look at reaction behaviors in greater detail. There are a bewildering array of possible reactions, but the truth is that most chemical reactions fall into a rather limited number of basic types. This is a good thing for the student of chemistry. Recognizing types simplifies our task greatly, and enables us to achieve a greater level of confidence with predicting and explaining the outcomes of chemical reactions.

The dissociation of a strong acid in solution is effectively complete, except in its most concentrated solutions. A weak acid is only partially dissociated, with both the undissociated acid and its dissociation products being present, in solution, in equilibrium with each other. The strength of a weak organic acid may depend on substituent effects. The strength of an inorganic acid is dependent on the oxidation state for the atom to which the proton may be attached. Acid strength is solvent-dependent. For example, hydrogen chloride is a strong acid in aqueous solution, but is a weak acid when dissolved in glacial acetic acid. Acid strengths also depend on the stability of the conjugate base.

Acids have long been recognized as a distinctive class of compounds whose aqueous solutions exhibit the following properties:. Acidic solutions have a pH less than 7, with lower pH values corresponding to increasing acidity. Common examples of acids include acetic acid in vinegar , sulfuric acid used in car batteries , and tartaric acid used in baking. The strength of an acid refers to how readily an acid will lose or donate a proton, oftentimes in solution. A stronger acid more readily ionizes, or dissociates, in a solution than a weaker acid.

7.1 Collisions and Chemical Reactions

There are three major classifications of substances known as acids or bases. This theory was developed by Svante Arrhenius in Later, two more sophisticated and general theories were proposed.

Acid—base reactions are essential in both biochemistry and industrial chemistry. Moreover, many of the substances we encounter in our homes, the supermarket, and the pharmacy are acids or bases. For example, aspirin is an acid acetylsalicylic acid , and antacids are bases.
