How do we make salts?
Answers
Explanation:
Normal Salt: A normal salt is a salt formed by the complete replacement of replaceable hydrogen atoms from an acid molecule by means of a metal or a group of elements acting like a metal. Examples: The compounds like KCl, NaCl, FeS04, Na2S04, FeCl2 etc are normal salts.

Answer:
Making salts from acids and bases:
A soluble salt can be prepared by reacting an acid with a suitable insoluble reactant including:
•♡a metal
•♡a metal oxide
•♡a carbonate
The insoluble reactant chosen depends upon the particular salt required. For example, copper does not react with dilute acids, so copper salts are made using copper(II) oxide or copper(II) carbonate, not copper metal. On the other hand, sodium is too reactive to be used safely - again the metal is not used to make sodium salts.
As the reaction between metals and acids produces flammable hydrogen, chemists usually make salts by reacting a metal oxide or a metal carbonate with an acid.
Naming Salts:
The name of a salt has two parts. The first part comes from the metal, metal oxide or metal carbonate. The second part comes from the acid:
■hydrochloric acid produces chloride salts
■nitric acid produces nitrate salts
■sulfuric acid produces sulfate salts
The table shows some examples of the salts produced by different combinations of insoluble reactants and acids.
