(a) Lactic acid
(b) Formic acid
(c) Tartaric acid
(d) Hydrochloric acid

Answer 1

Answer:

Option D) Hydrochloric Acid

Explanation:

A mineral acid is an acid derived from one or more inorganic compounds. They form hydrogen ions and the conjugate base ions when dissolved in water. Most common mineral acids are hydrochloric, nitric, sulfuric, and phosphoric acid. They are used for synthesis of other chemicals, removing the deposits from the inside of boilers in large plants, etc.

Answer 2

Among the given list (d) Hydrochloric acid is a mineral acid.

Explanation:

• The acids are broadly classified as organic acid and inorganic acid or mineral acid.
• The acids which are obtained from living sources such as plants and animals, and has carbon as one its component, they are called as organic acid.
• On the other hand, those acids that are formed due to combination of different elements in appropriate ratio under specific condition are called as inorganic or mineral acid.
• Lactic acid is obtained form plants, and certain microorganism. Thus it is an organic acid.
• Formic acid is present in the sting of the ant. Thus it is also an organic acid.
• The source of tartaric acid is tamarind. Hence it is also an organic acid.
• Hydrochloric acid is formed by fusion of hydrogen and chlorine and also lacks carbon. Thus it is a inorganic or mineral acid.
• Hence it is clear that among the given list (d) Hydrochloric acid is mineral acid.
