Definition Of Types Of Salts

Salts are ionic compounds that can result from the neutralization reaction of an acid and a baset

More About Types of salts

  • Orange and lemon are sour in taste because of the presence of acids in them. Mustard seeds contain some basic compounds and impart bitter taste to them
  • Overall the acidic and basic compounds are part of our everyday life
  • Acidic compounds could be identified by their sour taste while basic compounds are bitter in taste
  • There are several examples around us including our daily food which contain some or the other acidic and basic chemical substances
  • Sodium Chloride or table salt is produced from the neutralization reaction of Sodium Hydroxide (base) and Hydrochloric acid
  • Other examples of salts are Epsom salts (MgSO4) used in bath salts, Ammonium Nitrate (NH4NO3) used as a fertilizer and Baking Soda (NaHCO3) used in cooking
  • The chemical formula of salt derives from the formula of constituent acid and base. The positive ion of the salt comes from an acid while the negative part will come from the base
  • Salts are formed due to the combination of an anion and a cation from the base and acid respectively; and therefore the pH of the salt solution completely depends on the constituent acid and base from which the salt is formed
  • Sodium Chloride which is a neutral compound but baking soda that is Sodium Hydrogen Carbonate (NaHCO3) forms an alkaline aqueous solution
  • A salt that has neither hydrogen (H) nor hydroxyl (OH) in its formula, e.g., sodium chloride (NaCl), is called a normal salt
  • A salt that has hydrogen in its formula, e.g., sodium bicarbonate (NaHCO3), is called an acid salt
  • A salt that has hydroxyl in its formula, e.g., basic lead nitrate (Pb [OH] NO3), is called a basic salt
  • In addition to being classified as normal, acid, or basic, salts are categorized as simple salts, double salts, or complex salt
  • Simple salts contain only one kind of positive ion eg. MgCl2
  • Double salts contain two different positive ions, e.g., the mineral dolomite, or calcium magnesium carbonate, Ca Mg (CO3)2
  • Alums are a special kind of double salt
  • Complex salts, for example potassium ferricyanide k3Fe(CN)6 do not dissociate in aqueous solution
  • A hydrate is a salt that includes water in its solid crystalline form; Glauber's salt and Epsom salts are hydrates
  • Salts are often grouped according to the negative ion they contain, e.g., bicarbonate or carbonate, chlorate, chloride, cyanide, nitrate, phosphate, silicate, sulfate, or sulfide
