Insoluble salts can be prepared by?
- titrating an alkali against an appropriate acid
- reacting an acid with trioxocarbonate (IV) salt
- directing combination of the elements which make up the salt
-
mixing two soluble compounds containing the metallic radical and the acidic radical
The correct answer is: D
Explanation
An insoluble salt can be prepared by a precipitation method through a double decomposition reaction.
Two soluble metal salts react with each other to form one soluble salt and one insoluble salt .
Lead nitrate solution and sodium chloride solution react to produce solid lead chloride , leaving soluble sodium nitrate in solution.
The lead chloride can be recovered by filtration.
