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
