Unit 9 Acids and Bases

Explain what happens when a strong acid and a strong base are poured into the same container.

• they form separate layers
• they mix physically but not chemically
• they break apart into separate elements
• they react chemically to form a salt

When dissolved in water, bases produce:

• acids
• salts
• hydrogen ions
• hydroxide ions

Which statement is true when acids and bases are mixed together?

• acids become stronger
• bases become stronger
• there is no change
• they neutralize each other

When dissolved in water, acids produce:

• bases
• salts
• hydrogen ions
• hydroxide ions

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

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

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

Forms hydroxide ions (OH^-) in water

• Acids
• Bases
• All

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

• acidic
• basic

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

• acidic
• basic
