Acid-Base Titrations Problems

How will I ensure I get an accurate final end point?

• Be slow and careful 
• Repeat until you have 3 very similar titre
• Rinse the Burette
• Always use the same Pipette filler

Acid + Base ₋--> 

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

If phenolphthalein turns bright pink, it indicates

• an acid 
• a base
• a neutral

HCl + NaOH → 

• NaH + ClOH
• NaCl + H₂
• NaCl + H₂O
• NaCl + Cl₂

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

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

• 2.5mL
• 5mL
• 25mL
• 50mL

what is the reading on this burette?

• 4.40mL
• 3.50mL
• 3.60mL
• 4.50mL

I have 25mL of 1M HCl which neutralises 20mL of NaOH. What is the concentration of the NaOH?

• 0.8 M
• 1 M
• 1.25 M

What does pH measure?

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

A standard solution is a solution with accurately known concentration.

• True

• False
