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

pH less than 7.

• Acids
• Bases
• All

What are the products of the neutralization shown below?
Ca(OH)₂  +  H₂CO₃  -->  

• H₂O  +  Ca₂CO₃
• CaO +  CO₃
• H₂O  +  CaCO₃

What indicator is commonly used in titrations?

• Phenolphthalein
• Bromothymol Blue 
• Litmus
• Universal 

Identify the products of the chemical equation
3 LiOH + H₃PO₄ →

• Li₃PO₄ + 3 H₂O
• LiPO₄ + 3 H₂O
• Li(PO₄)₃ + 3 H₂O
• BOY + La + N₂

In a titration, 15.5 g of oxalic acid was dissolved in a flask and neutralized with 31.2 mL of NaOH.  Determine the molarity of the NaOH.

Hint: Primary standards (like oxalic acid, here) incude water in their formula.  As a result, they do not absorb atmospheric water.  Oxalic acid has the chemcial formula: H₂C₂O₄⋅2H₂O (so be sure to include the 2 extra water molecules).

• 7.88 mol/L
• 8.33 M
• 3.55 M
• 0.333 mol/L
