Question

Give the name and formula for the acid derived from each of the following anions: (a) perchlorate (b) N03- (c) bromite (d) H2PO4-

Answer 1

The acids derived from perchlorate, nitrate (NO3-), bromite, and dihydrogen phosphate (H2PO4-) anions are perchloric acid (HClO4), nitric acid (HNO3), bromous acid (HBrO2), and phosphoric acid (H3PO4), respectively.

Step-by-step explanation:

The acid derived from each of the following anions is:

• (a) perchlorate: The acid is perchloric acid, with the formula HClO4.
• (b) Nitrate (NO3-): The acid is nitric acid, with the formula HNO3.
• (c) bromite: The acid is bromous acid, with the formula HBrO2.
• (d) Dihydrogen phosphate (H2PO4-): The acid is dihydrogen phosphoric acid or simply phosphoric acid, with the formula H3PO4.

It is essential to recognize the systematic naming conventions for acids, which typically involve prefixes and suffixes based on the oxidation state of the central atom and the presence of oxygen in the polyatomic ion.

Answer 2

(a) Perchloric acid (HClO₄)

(b) Nitric acid (HNO₃)

(c) Bromous acid (HBrO₂)

(d) Phosphoric Acid (H₃PO₄)

Step-by-step explanation:

Acids are the species which furnish hydrogen ions in the solution. The other specie produced with the hydrogen ion is called its conjugate base.

Thus,

(a) Perchlorate (ClO₄⁻) ion:

The acid that furnish perchlorate ion is perchloric acid (HClO₄).

(b) NO₃⁻ ion:

The acid that furnish NO₃⁻ ions is Nitric acid (HNO₃).

(c) bromite (BrO₂⁻) ion:

The acid that furnish BrO₂⁻ ions is Bromous acid (HBrO₂).

(d) H₂PO₄⁻ ion:

The acid that furnish H₂PO₄⁻ ions is Phosphoric Acid (H₃PO₄).
