               Salts-
                    •  Salts are those compounds which are formed by the neutralization reaction
                       of an acid with a base.
                    •  Salts are electrically neutral.

                    •  Examples-
                              1.  HCl  +  NaOH   →   NaCl   +   H2O
                                  Acid          Base                    Salt            Water
                              2.  H2SO4   +   KOH   →   K2SO4  +  H2O
                                     Acid                Base                 Salt             Water
                              3.  HNO3  +   Mg(OH)2   →    Mg(NO3)2  +   H2O
                                  Acid                   Base                         Salt                    Water
                              4.  CH3COOH  +  NaOH  →   CH3COONa   +   H2O
                                           Acid                     Base                     Salt                    Water
                       As evident above,
                                      The type of SALT depends on the parent Acid & parent base.
                        SALTS may be characterised as–



               1.The family to which they belong                  2.Their Nature (Acidic/ Basic/ Neutral).

                    •  Family of Salt:

               Salts belonging to same family may have –



               1. Common acidic radicals                                           2. Common basic radicals


               Example:
                         Salts having common Acidic Radicals-
                     1.  Sodium chloride (NaCl) and Calcium chloride (CaCl2) → Chloride
                         family.
                     2.  Potassium sulphate (K2SO4)  and Magnesium Sulphate (MgSO4) →
                         Sulphate Family
                     3.  Silver Nitrate (AgNO3) and Copper Nitrate (Cu(NO3)2)  → Nitrate Family
