Answer to Question #165750 in General Chemistry for Phyroe

Question

Give equations showing how the following molecules and ions may act as acids:

HClO4, HSO4-, HCO2-, H2O, HPO4-

Answer 1

1)H₂O + HClO₄ = H₃O⁺ + ClO₄^-

2) HSO₄^-​ is an anion it forms H₂SO₄ when exposed to H₂O

3) CHO₂^- + H⁺ = CH₂​O₂

4) H₂​PO₄^- is an acid and when it is in water it forms a hydronium ion and HPO₄^-, which is the conjugate base.

5) As the proton donor, H₂O acts as a Bronsted-Lowry acid. For example NH₃ + H₂O = NH₄⁺ + OH^-
