A salt is formed when strong ionic bonds held a cation from base and anion from acid together as below:

 

                          electrostatic attraction                                                                                                                          ionic bond   

     Sodium ion,Na+ from                      Chloride ion,Cl- from                                                                                       Sodium chloride, NaCl

sodium hydroxide, NaOH                   hydrocloric acid,HCl                                                                                        (A salt=ionic compound)

     (cation from base)                          (anion from acid)
