Titrations and Calculations

What is this piece of apparatus called

• Pipette

• Burette

• Janette

• Cuvette

What allows us to know when the end point has been reached?

• Bubbles

• Feels warm

• indicator changing color

• Turns to a solid

What is the reading on this burette?

• 4.40mL
• 3.50mL
• 3.60mL
• 4.50mL

I have 25mL of 1.0 mol/L HCl which neutralises 20mL of NaOH. What is the concentration of the NaOH?

• 0.8 mol/L

• 1 mol/L

• 1.25 mol/L

I am titrating 1M HCl with 1M NaOH.  I have 25mL of HCl. How much NaOH will I need?

• 2.5mL
• 5mL
• 25mL
• 50mL

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

• Acid
• Base
• Neutral
• Acid and Base

A titration works by using a ___________________________ reaction.

• Single Replacement

• Neutralization

• Combustion

• Synthesis

What is the endpoint of a titration

• Where the amount of acid and base are balanced according to the equation
• Where there is no base
• At the end

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

A 25.0 mL sample of HCl was titrated to the endpoint with 15.0 mL of 2.0 mol/L NaOH. What is the concentration of HCl?

• 1.6 mol/L

• 0.03 mol/L

• 0.6 mol/L

• 1.2 mol/L
