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)
Salts also produced from neutralization or titration reaction between acids and alkalis/bases:
ACID + ALKALI/BASE neutralization SALT + WATER
|Hydrochloric acid, HCl||Chlorides: NaCl, KCl, ZnCl2, AgCl, CuCl2, NH4Cl|
|Nitric acid, HNO3||Nitrates: NaNO3, KNO3, Mg(NO3)2, AgNO3,Cu(NO3)2, NH4NO3|
|Sulphuric acid, H2SO4||Sulphates: Na2SO4, K2SO4, ZnSO4, CuSO4, MgSO4, Al2(SO4)3, (NH4)2SO4|
|Ethanoic acid, CH3COOH||Ethanoates: CH3COONa, (CH3COO)2Zn|
|Carbonic acid, H2CO3||Carbonates: Na2CO3, K2CO3, ZnCO3, CuCO3, (NH4)2CO3|
H3PO4 (tripotic acid) NaH2PO4, Na2HPO4 and Na3PO4 (salts)
Thousands of salts exist naturally in earth.
For example salts like sodium chloride, magnesium chloride, magnesium sulfate, sodium chloride, and sodium bromide exist in sea water.
While salts like calsium fluoride, magnesium sulfate, and lead (II) sulfide exist as mineral in earth crust.
Salts that not exist naturally can be made and produced through chemical method in chemical industry.
