Describe the solution at 25 °C with pOH = 5.3.

The use of a single arrow in the following chemical equation illustrates that the strong acid completely ionized. HBr(aq) + H2O(l) —–> H3O+ (aq) + Br- (aq)

Water is a reactant in the ionization of a weak acid, so [H2O] is included in the equation for the ionization constant for that weak acid.

Identify the Brønsted-Lowery Acid in the following reaction. H2SO4(aq) + NH3(aq) —– > 2 NH4+(aq) + SO42-(aq)

What is the hydroxide ion concentration of a solution at 25 °C that has a pH = 9.13?

A Bronsted-Lowery acid donates a proton, H+, to another compound.

Determine the pH of a solution in which the hydronium ion concentration is 3.5 x 10-4 M.

A group of students were asked if they carry a credit card.  The responses are listed below in the table. If a student is a selected at random, find the probability that the student owns a credit card given that the student is a freshman.  Round your answer to three decimal places.
