Definition Name | Proponent | Definition | Concept | Limitations |
Arrhenius Acids | Svante Arrhenius | A substance which increases the concentration of hydronium ion H3O+ when it is dissolved in water is an Arrhenius acid. | Equilibrium disassociation of water into hydroxide and hydronium ions. | Failure to recognize transfer of proton involved in acid-base reactions. |
Brønsted-Lowry Acids | Johannes Nicholaus Brønsted & Thomas Martin Lowry | Any substance that gives a proton away to a Brønsted-Lowry base is a Brønsted-Lowry acid. | Transfer of proton from acid to base. | Failure to recognize electron pair acceptance. |
Lewis Acids | Gilbert Lewis | A substance that accepts a couple of electrons from another substance is a Lewis acid. | Inclusion of those acid base reactions which do not involve proton transfer. | Unless specifically expressed, all acid-base reactions are assumed to rely upon the transfer of a proton from acid to base, thereby, rendering the Brønsted-Lowry definition more popular. |
- Acids and acidic compounds taste sour and give off an acrid odor. Take, for instance, vinegar. You can smell the stinging sour odor as soon as you open a bottle of vinegar and we all know how vinegar tastes!
- All acids and acidic compounds react with metals and such reaction always results in the production of hydrogen.
- Acids are good conductors of electricity and are so corrosive that they tend to eat away at most things which come in contact with them.
- Some acids give away one proton each molecule during dissociative processes and such acids are called Monoprotic acids.
- Some acids lend more than one protons per molecule during disassociations and such acids are called Polyprotic Acids.
- One of the most remarkable chemical properties of acids and bases is that they react with each other to produce salts. This process is known as neutralization. For instance, hydrochloric acid would react with sodium hydroxide to produce salt (sodium chloride) and water!
- Acids are soluble in water and an acid can be either a strong acid or a weak acid. A strong acid is that which ionizes completely in a water solvent solution by the renunciation of one proton. Sulfuric acid, hydrobromic acid and hydrochloric acid are prominent examples of strong acid. Sulfuric acid uses range from their use in car batteries, fertilizers and as industrial catalysts. Hydrochloric acid in stomach manifests as gastric acids. A weak acid is that which ionizes incompletely and does not release all the hydrogen it contains. It lends only some amounts of its proton to an aqueous solution. Good examples of weak acid are acetic acid and boric acid. Phosphoric acid is also a weak acid and phosphoric acid uses include rust removal, acidifying food and beverages and as a pH adjuster in several cosmetics, among others.
