Question

What is an acid? Write four properties of acids by giving examples.

Answer 1

Hint: Any hydrogen-containing material capable of transferring a proton (hydrogen ion) to another chemical is classified as an acid. A base is a molecule or ion that can take a hydrogen ion from an acid and accept it. Acidic substances are characterized by a sour flavor.

Complete answer:
Acids: Acid is any material that alters the color of certain indicators (e.g., reddens blue litmus paper), reacts with some metals (e.g., iron) to liberate hydrogen, combines with bases to produce salts, and stimulates certain chemical reactions in a water solution (acid catalysis). Mineral acids such as sulfuric, nitric, hydrochloric, and phosphoric acids, as well as organic molecules belonging to the carboxylic acid, sulfonic acid, and phenol groups, are examples of acids. One or more hydrogen atoms are present in such compounds, which are discharged as positively charged hydrogen ions in solution.
Four properties of acids:
Acids are naturally corrosive. (e.g., hydrochloric acid, sulfuric acid, nitric acid)
They are excellent electrical conductors. (e.g., Hydrochloric acid and sulphuric acid)
The pH of acids is always less than 7. (e.g. sulfuric acid, phosphoric acid, nitric acid)
Acids have a sour taste to them. (e.g., acetic, citric, malic, fumaric acid).

Note:
When working with acids and bases, use safety equipment such as goggles, long-sleeved clothing, and gloves. Acids and bases should not be allowed to come into contact with the skin or eyes. Limit the number of acids and bases brought into the house for use. Acid and base cleaner bottles should be properly closed.
