What is a buffer solution?
A solution that resists changes in pH when small amounts of acid or base are added
A solution that has a high concentration of hydrogen ions
A solution that contains both an acid and its conjugate base
A solution that has a low concentration of hydrogen ions
What is the molarity of a 0.1 M NaCl solution?
0.1 mol/L
1 mol/L
10 mol/L
100 mol/L
What is the difference between a normal solution and a molar solution?
A normal solution is a solution with a concentration of 1 mole per liter while a molar solution is a solution with a concentration greater than 1 mole per liter
A normal solution is a solution with a concentration greater than 1 mole per liter while a molar solution is a solution with a concentration of 1 mole per liter
There is no difference between a normal solution and a molar solution
A normal solution is a solution with a concentration less than 1 mole per liter while a molar solution is a solution with a concentration of 1 mole per liter
What is the purpose of a pH meter?
To measure the acidity or alkalinity of a solution
To measure the temperature of a solution
To measure the conductivity of a solution
To measure the viscosity of a solution
How does a glass electrode work?
It measures the potential difference between two electrodes immersed in a solution
It measures the current flowing through a solution
It measures the voltage across a solution
It measures the resistance of a solution
What is the advantage of using a colomel electrode over a glass electrode?
It is more accurate and sensitive
It is cheaper
It is easier to use
It is faster
What is the range of a typical pH meter?
0-14
-14-14

What is the formula for calculating the pH of a solution?
PH = -log[H+]
PH = log[H+]
PH = [H+]
PH = -[H+]
