An overview of common acids and bases

Whereas alkali, which is a more general term used for bases are bitter, and change the colour of the red litmus to blue. Acid catalysis Acids are used as catalysts in industrial and organic chemistry; for example, sulfuric acid is used in very large quantities in the alkylation process to produce gasoline.

Overview of Acids and Bases - Chemistry Chapter Published 2 months ago Understanding acids and bases is important in chemistry. The term acid, in fact, comes from the Latin term acere, which means "sour". Acid plus base makes water plus a salt. Arrhenius concept of acids and bases 2.

Ammonia and its derivatives are common examples for Lewis bases. Phosphoric acidfor example, is a component of cola drinks. Extreme pH values, either above or below 7. An example is the weakly acidic ammonium chloridewhich is produced from the strong acid hydrogen chloride and the weak base ammonia.

Acids and Bases

Acid catalysis Main article: Acids neutralize bases in a neutralization reaction. Applications of acids There are numerous uses for acids. Arrhenius bases are substances which produce hydroxide ions in solution. Bases neutralize acids in a neutralization reaction.

Sour milk, sour cream, yogurt, kimchi, and cottage cheese have lactic acid from the fermentation of the sugar lactose. Consider the following chemical equation: Acids are used as additives to drinks and foods, as they alter their taste and serve as preservatives.

Henderson—Hasselbalch equation In order for a protonated acid to lose a proton, the pH of the system must rise above the pKa of the acid.

Certain acids are used as drugs. The Lewis acids are those which can accept a lone pair of electrons. However, in the ammonia case, there are no hydroxide ions!

Citric acid is used as a preservative in sauces and pickles. Properties Of Bases Bases release a hydroxide ion into water solution. Carbonic acid is important for maintenance of pH equilibrium in the body. Water H2O can be both an acid and a base.


Additionally, carboxylic acids can be esterified with alcohols, to produce esters. Bases turn red litmus to blue. They may be used as an electrolyte in a wet cell batterysuch as sulfuric acid in a car battery.

This is not to say that litmus is the only acid - base indicator, but that it is likely the oldest one. Conversely, neutralizing a weak acid with a strong base gives a weakly basic salt, e. Acids corrode active metals.

This accounts for the "slippery" feeling on hands when exposed to base. Water is a good example for this.Properties Of Acids.

Acids and Bases: An Introduction

For the properties of acids and bases we will use the Arrhenius definitions. Strong Acids And Strong Bases.

In the Brønsted-Lowry definition of acids and bases, a base is defined as a compound that can accept a proton. However, how does it accept the proton? One feature that Brønsted-Lowry bases have in common with each other is that they have an unshared pair of electrons.
