Answer 2

Classification of Acids:

To classify the given formulas of acids, we need to determine the number of hydrogen atoms (H) that can be replaced by metal or positive ions. Based on this, acids can be categorized as follows:

1) Monoprotic acids (or one-protic acids): These acids can donate only one hydrogen ion (H+) per molecule. Examples include HNO3 (nitric acid) and HCl (hydrochloric acid).

2) Diprotic acids (or two-protic acids): These acids can donate two hydrogen ions (H+) per molecule. Examples include H2SO3 (sulfurous acid).

3) Triprotic acids (or three-protic acids): These acids can donate three hydrogen ions (H+) per molecule. An example is H3PO4 (phosphoric acid).

Now, let's classify the given formulas of acids based on this classification:

A) H3PO4: This formula represents phosphoric acid, which is a triprotic acid. It can donate three hydrogen ions (H+) per molecule.

B) H2SO3: This formula represents sulfurous acid, which is a diprotic acid. It can donate two hydrogen ions (H+) per molecule.

C) HNO3: This formula represents nitric acid, which is a monoprotic acid. It can donate one hydrogen ion (H+) per molecule.

D) H2Se: This formula represents selenous acid, which is a diprotic acid. It can donate two hydrogen ions (H+) per molecule.

E) HCl: This formula represents hydrochloric acid, which is a monoprotic acid. It can donate one hydrogen ion (H+) per molecule.

Therefore, the classification of the given formulas of acids is as follows:

A) H3PO4: Triprotic acid B) H2SO3: Diprotic acid C) HNO3: Monoprotic acid D) H2Se: Diprotic acid E) HCl: Monoprotic acid
