🧲 Neutralization/Titration & Acid/Base Naming

A neutralization reaction will (almost) always produce...

• water & salt
• water
• salt
• water & carbon

If there is excess hydrogen ions, the solution will be...

• acidic
• basic

Identify the salt in the following equation:
Zn(OH)₂ + HNO₃   ---> H₂O  + Zn(NO₃)₂

• Zn(OH)₂
• HNO₃
• H₂O
• Zn(NO₃)₂

Complete the following (unbalanced) reaction:

HCl + Mg(OH)₂ -->

• MgCl₂ + H₂O

• Mg +H₂O

• MgCl₂ + H₂

• MgCl₂ + H₂O + CO₂

What is the endpoint of a titration?

• Where the amount of acid and base are equal as shown by a color change

• Where there is no base

• When the volume of base in the burette is used up

• When there is no acid

How many moles of Ca(OH)₂ are needed to neutralize three moles of HCl? 

• 8
• 1.5
• 6
• 3

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 this piece of apparatus called?

• Pipette

• Buret

• Cylinder

• Flask

1) 0.04 M NaOH is load into a buret - initial reading is 4.5 mL

2) 60 mL of amonoprotic acid, HBr, is placed in a flask under the buret.

3) 2 drops of phenolphthalein is added to the flask.

4) The base is slowly added to the acid until it turns pink. - final reading from the buret is 34.6 mL.

WHAT IS THE MOLARITY OF THE ACID?

• 0.04 M

• 0.0012 M

• 0.02 M

• 30.1 M

A 50.0 mL sample of Ca(OH)₂ is neutralized by 300.0 mL of HCl solution with a pH of 1.3. Calculate the molarity of the Ca(OH)₂ solution.

• 1.0 M
• 0.50 M
• 0.15 M 
• 0.30 M
