Making Salts
Q1.
Salts can be prepared by the reaction of acids with alkalis.
(a)     (i)      The reactions of acids with alkalis can be represented by the equation below. Choose a substance from the box to complete the equation.
 
carbon dioxide     hydrogen     oxygen    water	
acid  +  alkali  →  salt  +  _____________________________
(1)
(ii)     Draw a ring around the word which best describes the reaction.
displacement       neutralisation       oxidation       reduction
(1)
(b)     Sodium sulphate is an important salt.
          The table gives a list of some substances.

Q2.
Ammonium nitrate and potassium chloride are both salts. They can be made by neutralisation reactions.
          Choose substances from the box to complete the word equations for the formation of these two salts.
 
ammonia              hydrochloric acid          nitric acid
potassium nitrate            water          potassium hydroxide	
ammonia  +  ____________________  →  ammonium nitrate  +  water
_________________ + hydrochloric acid → potassium chloride + _____________
