In a neutralization reaction, what are the products of a reaction between an acid and a base?

• Another acid and base
• Carbon dioxide and a salt
• Water and a salt
• Either two acids or two bases

The pH scale measures...

• ...the strength of an acid.
• ...the strength of hydrogen ions.
• ...the concentration of hydrogen ions.
• ...the concentration of an acid

What is a titration?

• when the moles of hydrogen ions is equal to the moles of hydroxide ions

• adding a known amount of solution of known concentration to determine the concentration of an unknown

• reaction in which an acid and a base react in an aqueous solution to produce a salt and water

• the extent of ionization of an acid or base

Defined acids and bases in terms of protons.

• Arrhenius

• Bronsted-Lowry

• Lewis

• Avogadro

The conjugate of a strong base is a
