Acids, bases, and salts

Citric acid in fruits such as oranges and lemons and tartaric acid found in tamarind are examples of acids and bases found naturally in nature. Other acids and bases include lactic acid in milk and milk products, hydrochloric acid in gastric juices, and acetic acid found in lactic acid. Many bases, such as lime water, can be found. Many of these acids are used in our daily lives, such as vinegar or acetic acid in the kitchen, boric acid for laundry, baking soda for cooking, and washing soda for cleaning, among other things.

Definitions

Acid:- An acid is defined as a substance whose water solution has a sour taste, turns blue litmus red, and neutralises bases when mixed with other acids or bases.
Base:- A substance is referred to as a base if its aqueous solution has a bitter taste, turns red litmus blue, or has the ability to neutralise acids. Aqueous solution of salt has no effect on the litmus test because salt is a neutral substance. When the acid is dilute hydrochloric acid and the metal is iron, we have a successful reaction. The addition of dilute hydrochloric acid to the iron filings results in the formation of iron (II) chloride and hydrogen. With the help of hydrochloric acid, iron takes the place of hydrogen, resulting in the formation of ferric chloride and hydrogen. This reaction is a straightforward displacement reaction involving gas. Ammonium chloride (chemical formula NH4Cl) is classified as an acid salt because it is a salt of a strong acid (in this case, hydrochloric acid) and a weak base (in this case, sodium chloride) (i.e. ammonium hydroxide).

Acids

‘acidus’ or ‘acere’ is a Latin word that means sour, and the term acid is derived from this word. The sour taste of these fruits is the most common characteristic. An acid is a substance that, when present in aqueous solution, causes the formation of the ionizable hydronium ion (H3O+). It causes the blue litmus paper to turn red. Examples of how these dissociate in aqueous solution to form their constituent ions are provided in the following section. Depending on where they occur, they can be divided into two categories: natural acids and mineral acids. Natural acids: These are obtained from natural sources, such as fruits and animal products, and are considered healthy. For example, lactic, citric, and tartaric acids are all types of acids. Mineral Acids: Mineral acids are acids that occur naturally in the environment. Mineral acids are acids that are derived from minerals in some way. For example, hydrochloric acid (HCl), sulphuric acid (H₂SO₄), and nitric acid (HNO₃), among other acids, are used in manufacturing.

Bases

Bases are distinguished by their bitter taste and soapy feel, which are the most common characteristics. A base is a substance that causes the formation of the hydroxyl ion (OH^–) in its aqueous solution. Bases change the colour of red litmus paper from red to blue when exposed to them.

Salts

Sodium chloride is an ionic compound that is formed as a result of the neutralisation reaction between acids and bases. In nature, salts are composed of positively charged ions, known as cations, and negatively charged ions, known as anions. Cations and anions can be found in both organic and inorganic forms. These ions are present in a relatively small amount, and as a result, the nature of the salt is rendered neutral.

Conclusion

Numerous acids and bases that we do not consume in the home are used in laboratories and industries, and these include acids such as HCl, H₂SO₄, and bases such as NaOH, KOH, and other similar compounds, among others. Because of the neutralisation reaction that occurs when these acids and bases are mixed in the proper proportions, salt and water are formed as a result of the reaction. Seawater and natural rock deposits contain a variety of naturally occurring salts such as sodium chloride (NaCl) and potassium chloride (KCl).
