Bases that partially ionize in water are:

A chemist prepares an aqueous solution of sodium chloride, NaCl(aq).  The solution contains 50.0 g of NaCl and has a volume of 450 mL.  What is the molarity of this solution?

A compound that increases [OH-] in an aqueous solution is a(n):

Airbags rapidly-produce nitrogen gas through reactions like this one: 2 NaN3(s) → Na(s) + 3 N2(g) In this reaction, what volume of nitrogen gas can be produced by the reaction of 13.0 g of NaN3, if the temperature is 350 K and the pressure is 1.2 atm?  (Hint: The molar mass of NaN3 = 65 g/mol)

The pH of an unknown solution is 2.1.  What is the [OH-]?

The driving force of a neutralization (or acid-base) reaction is the formation of _______.

Identify the Brønsted-Lowry base in this reaction: H2O(l) + HNO3(aq) → H3O+(aq)  + NO3-(aq)

Identify the Brønsted-Lowry acid in this reaction: H2SO4(aq) + HNO3(aq) → HSO4-(aq) + H2NO3+(aq)

Select the greatest pressure.
