Answer:
(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).
