When hydroiodic acid (HI) is added to water, hydronium ions and iodide ions are formed. Which of the following statements is true?
iodide acts as an conjugate acid; hydronium acts as a conjugate base
hydronium acts as an acid; iodide acts as a base
hydronium acts as an conjugate acid; iodide acts as a conjugate base

In basic solution:
[OH-] = 0 M
[H3O+] < [OH-]
[H3O+] = [OH-]
[H3O+] > [OH-]
In a laboratory titration, 25.0 mL of NaOH is completely neutralized by 14.2 mL of 0.500 M HCl. What is the concentration of the NaOH solution?
An aqueous solution contains 0.10 M NaOH. This solution is:
Nitric acid is a strong acid. This means that:
HNO3 dissociates completely to H+(aq) and NO3-(aq) when it dissolves in water
HNO3 cannot be neutralized by a weak base
HNO3 produces a gaseous product when it is neutralized
HNO3 does not dissociate at all when it is dissolved in water
What is the pH of an aqueous solution that contains 3.98 x 10-9 M H+?
