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

(a) Perchloric acid (HClO₄)

(b) Nitric acid (HNO₃)

(c) Bromous acid (HBrO₂)

(d) Phosphoric Acid (H₃PO₄)

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).
