Acids and Bases

Front

What do acids react with to produce salts and water?

Back

Acids react with bases to produce salts and water.

Front

What is the pH of a solution with an [OH-] concentration of 1x10^-12 M?

Back

The pH of the solution is 2.0.

Front

What substance releases hydrogen ions in an aqueous solution?

Back

An acid releases hydrogen ions in an aqueous solution.

Front

What is the purpose of a titration?

Back

A titration is used to determine the concentration of an unknown solution by adding a known amount of solution of known concentration.

Front

What type of compound is HNO2?

Back

HNO2 is an acid.

Front

Define an acid in terms of its behavior in water.

Back

An acid is a substance that donates hydrogen ions (H+) in an aqueous solution.

Front

What is the relationship between pH and [H+] concentration?

Back

pH is the negative logarithm of the hydrogen ion concentration: pH = -log[H+].

Front

What is a strong acid?

Back

A strong acid is one that completely dissociates in solution, releasing all of its hydrogen ions.

Front

What is a weak acid?

Back

A weak acid partially dissociates in solution, meaning not all of its hydrogen ions are released.

Front

What is the pH range of acidic solutions?

Back

The pH range of acidic solutions is from 0 to 7.
