Salts play a very important role in our daily life. Sodium chloride which is known as common salt is used almost in every kitchen. Baking soda is also a salt used in faster cooking as well as in baking industry. The family of salts is classified on the basis of cations and anions present in them.
(a) Identify the acid and base from which Sodium chloride is formed.
(b) Find the cation and the anion present in Calcium sulphate.
(c) "Sodium chloride and washing soda both belong to the same family of salts." Justify this statement.
Solution
(a) Acid – HCl, Base – NaOH
(b) Cation Ca2+, Anion SO4(2-)
(c) Salts having same cations but different anions belong to the same family of salts. e.g. sodium chloride (NaCl) and Washing Soda/sodium carbonate (Na2CO3) both have Na+ as cation.
