Indicators & Titrations PRACTICE

acid + base ₋>

• salt + hydrogen
• salt + water
• salt + carbon dioxide + water
• salt

What does pH measure?

• Amount of Oxygen Ions
• Amount of Hydrogen Ions
• The amount of salt in a solution
• The density

A solution with a pH of 8.6 would be...

• Acid
• Base
• Neutral
• Acid and Base

Why do we perform a titration?

• To determine the concentration of an unknown solution

• To see if a reaction will occur between an acid and base

• To find the mass of an unknown acid

• To find the molar mass of an unknown solution

• To calculate the viscosity of the solution

If it takes 54 mL of 0.1 M NaOH to neutralize 125 mL of an HCl solution, what is the concentration of the HCl? (record you answer with the correct unit)

• 0.043 M

• 0.034 M

• 0.065 M

• 0.77 M
