LQ58 Titration

What is this piece of apparatus called

• Pipette

• Burette

• Janette

• Cuvette

What indicator is commonly used in titrations?

• Phenolphthalein
• Bromothymol Blue 
• Litmus
• Universal 

If phenolphthalein turns bright pink, it indicates

• an acid 
• a base
• a neutral

What type of reaction is taking place here

• fertiliser

• titration

• acid

• neutralisation

What is the pH at the equivalence point.

• The pH is approximately 5 
• The pH is approximately 6 
• The pH is approximately 8 
• The pH is approximately 9 

The following neutralization reaction occurs in the classroom.
HCl  +  KOH  -->  H₂O  +  KCl
If a student uses 25.0 mL of a 0.5M solution of KOH, what is the molarity of the acid if the is 15.0mL of acid neutralized?

• 0.8M
• 1.2M
• 12.5M

What is the endpoint of a titration

• Where the amount of acid and base are equal as shown by a colour change 
• Where there is no base
• When the volume of base in the burette is used up 
• When there is no acid
