Water is amphiprotic: it can act as an acid by donating a proton to a base to form the hydroxide ion, or as a base by accepting a proton from an acid to form the hydronium ion (H3O+). The autoionization of liquid water producesOH− and H3O+ ions. How do H+ ions exist in nature?

In chemistry, what is an acid? What are [H^+] and [OH^-] for 0.01 M perchloric acid? What are H^+ \text{ and } OH^- for 0.01 M perchloric acid? If an 0.23 M solution of acid gives pH=3.82, what is K_a for acid?
According to Arrhenius, acids are compounds that break up in water to give off hydronium (H+) ions. A common example of an Arrhenius acid is hydrochloric acid (HCl): HCl ⇔ H+ + Cl- The formulas for acids usually start with hydrogen, though organic acids are a notable exception. The...
