Chemical Compounds
Chemical Compounds:
The chemical compounds around us can easily be categorised as Acids, Bases and Salts. Acids, Bases and Salts are compounds which occur naturally and can also be created artificially. They are found in various substances including our food. Vinegar or acetic acid is used as a food preservative. Citrus fruits have citric acid and etc.
Other than food they also have a wide variety of uses such as in various industries, manufacturing plants, processing plants, laboratories and others.
What is Acids?
An acid is a molecule that can contribute an H+ ion while also remaining energetically favourable after losing that ion. e.g. Sulfuric acid (H<sub>2</sub>SO<sub>4</sub>), Acetic Acid (CH<sub>3</sub>COOH), Nitric Acid (HNO<sub>3</sub>) etc.
What are Bases?
Bases are chemical compounds that react chemically with acids, they produce salts and hydroxide ions (OH<sup>–</sup>) in water. For example Potassium hydroxide (caustic potash or KOH), Calcium hydroxide (Ca(OH)<sub>2</sub>), Sodium hydroxide (caustic soda or NaOH) etc.
What are Salts?
When an acid and a base react to neutralise one another, they generate sales, which are ionic substances. Salts do not have an electrical charge. Salts come in a variety of forms, the most common of which is sodium chloride. Table salt and common salt are both terms for sodium chloride. Sodium chloride is used to make dishes taste better.
