A salt is a compound formed by the partial or complete neutralization of an acid by a base. Some salt are salty while most of them taste bitter. Sodium chloride, Potassium chloride, calcium chloride, calcium sulphate, etc. are some examples of salts.
Properties of salts
Preparation of salts
Salts can be prepared in many ways. Some methods of preparing salts are given below:
|1.||Sodium chloride||As edible salts (table salt, rock salt)|
|2.||Copper sulphate||As insecticides|
|3.||Magnesium sulphate||Used in constipation|
|4.||Calcium sulphate||Plastering fractured bones, in the manufacture of chalk.|
The properties of salt are as follows:
Indicator is defined as the chemical compounds used for identifying whether a given substance is acidic or basic in nature.
Salt is a compound formed by partial or complete replacement of hydrogen of an acid by a metal.
Water soluble metallic oxides of bases are called alkalis.
Sodium carbonate – Na2CO3
Sodium chloride – NaCl
Aluminum hydroxide – Al(OH)3
Potassium hydroxide – KOH
Sulphuric acid – H2SO4
Calcium sulphate – It is used as insecticide.
Magnesium sulphate – It is used for reducing constipation.
Aluminum hydroxide – It is used as medicine to get rid of gastric.
Sulphuric acid (H2SO4) is a compound which gives hydrogen ion and sulphate ion in solution state.
Methyl orange is changed into red colour after treating with this compound. H2SO4 +2NaOH → Na2SO4 + H2O
