What is acid and what are its characteristics.....

$\bf\huge\ AnSwEr:-$

.Acids are ionic compounds that, when dissolved in water, produce positive hydrogen ions ( H+) When dissolved in water, acids taste acidic, conduct electricity and react with metals to create hydrogen gas. Certain indicator compounds may be used to detect acids, such as litmus.

Answer 2

Answer:

Hii..

Acids:-

An acid is any hydrogen-containing substance that is capable of donating a proton (hydrogen ion) to another substance. A base is a molecule or ion able to accept a hydrogen ion from an acid.

Acidic substances are usually identified by their sour taste. An acid is basically a molecule which can donate an H+ ion and can remain energetically favourable after a loss of H+. Acids are known to turn blue litmus red.

Characteristics of Acids:-

• pH level < 7.0 (at RTP).

• A substance that when added to water increases the number of H+ ions in the water (Arrhenius).

• Is a proton donor (Brønsted-Lowry).

• Can accept an electron pair from a donor compound (Lewis).

• Reacts with bases to form salts.

• Turns blue litmus red

• Example: HCl.
