Semester Exam Review 3

Front

What is the pH of a solution with an H+ concentration of 0.00005 M?

Back

The pH is 4, indicating the solution is acidic.

Front

What does the equation PV=nRT represent?

Back

The Ideal Gas Law, which relates pressure (P), volume (V), number of moles (n), gas constant (R), and temperature (T).

Front

What happens to the volume of a gas when temperature decreases?

Back

The volume decreases, as described by Charles's Law.

Front

How do you calculate pOH from H+ concentration?

Back

pOH = 14 - pH; for [H+] = 8.4 x 10^-3 mol/L, pOH = 11.92.

Front

What occurs when an acid and a base are mixed?

Back

They neutralize each other, forming water and a salt.

Front

Define an acid in terms of H+ ions.

Back

An acid is a substance that increases the concentration of H+ ions in a solution.

Front

Define a base in terms of OH- ions.

Back

A base is a substance that increases the concentration of OH- ions in a solution.

Front

What is Boyle's Law?

Back

Boyle's Law states that pressure and volume of a gas are inversely related at constant temperature.

Front

What is Charles's Law?

Back

Charles's Law states that the volume of a gas is directly proportional to its temperature at constant pressure.

Front

What is the relationship between pH and pOH?

Back

pH + pOH = 14.
