Neutralization Practice

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 reaction:

HCl + Mg(OH)₂ -->

• MgCl₂ + H₂O

• Mg +H₂O

• MgCl₂ + H₂

• MgCl₂ + H₂O + CO₂

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

• Burette

• Janette

• Cuvette

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

2) 60 mL of unknown monoprotic acid, HA, is placed under the buret.

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

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

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

• acidic
• basic

If the pH of a solution is 5.6 the pOH is

• 6.5
• 12.4
• 8.4
• 5.6

What is the molarity of a 30 mL HCl which is neutralized by 48 mL of 0.1 M NaOH?

HCl + NaOH --> H₂O + NaCl

• 0.16 M

• 6.25 M

• 0.063 M
