Question

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

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

Answer 1

1.)$H2O + HClO4 \rightarrow H3OClO4$

2.) $HSO_4^-$ is an anion it forms $H_2SO_4$ when exposed to $H_2O$

3.) $CHO_2^- + H^+ \rightarrow CH_2O_2$

4.) $H_2P0_4^-$  is an acid and when it is in water it forms a hydronium ion and $HPO_4^-$ , which is the

conjugate base.

5.) The water molecule donates a proton to the NO₂⁻ ion, making OH⁻(aq) . As the proton donor, H₂O acts as a Bronsted-Lowry acid.
