Which substance is a binary acid?

Choose the correct option:

a) hydrochloric acid

b) phosphoric acid

c) nitrous acid

d) sulfuric acid

Correct Answer:

hydrochloric acid

Hydrochloric acid is classified as a binary acid. Binary acids or Hydracids are specific molecular compounds where hydrogen is combined with a second nonmetallic element. In the case of hydrochloric acid, it consists of hydrogen and chlorine. This acidic solution is commonly used in various industrial processes, laboratory experiments, and even in the digestive system.

The formula for hydrochloric acid is HCl, which represents its chemical composition of one hydrogen atom and one chlorine atom. When dissolved in water, it forms a strong acid that can react with metals, neutralize bases, and has a distinctive pungent odor. Due to its properties, hydrochloric acid plays a significant role in many chemical reactions and industries.

Understanding binary acids like hydrochloric acid is essential in chemistry as they form the basis for studying acidic properties, reactions, and chemical bonding. By recognizing the characteristics of binary acids, scientists and students can grasp fundamental concepts in chemistry and apply them to practical scenarios.

Next time you encounter the term "binary acid," remember that hydrochloric acid is a prime example of this category with its unique composition and versatile applications in the scientific world.
