Neutralization Reactions

(EmSAT/2021) what is the pH of the soil?

• 3

• 7

• 8

• 10

(EmSAT/nd) If the soil is too acidic, it can be treated with:

• HCl

• H2SO4

• Ca(OH)2

• NaCOOH

(EmSAT/2019) A neutralization reaction will almost always produce...

• water & salt

• water

• salt

• water & carbon

(EmSAT/nd) 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

Complete the following reaction:

H₃PO₄ + NaOH -->

• Na₃PO₄ + H₂O

• Na +H₂O

• Na₃PO₄ + H₂

• Na₃PO₄ + H₂O + CO₂

What is this piece of apparatus called

• Pipette

• Burette

• Janette

• Cuvette

(EmSAT/2020) 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

(EmSAT/2022) Antacid tablets are taken to:

• To neutralize the blood pH

• To Neutralize the acidity of the stomach

• To lower the pH of the blood

• To prevent acidosis

What is a neutralization reaction?

• Reaction between metals and acids

• Reaction between metals and oxygen

• Reaction between acids and bases

• Reaction between organic compounds and water
