Question

Define a mixed salt. Give two examples of mixed salt.

Answer 1

Hint: Salt is an inorganic compound consisting of an anion and cation. The anion is other than hydroxide and cation is other than proton. They are different types of salts. Mixed salt is one of the categories of salt in which the salt consists of a fixed proportion of two salts, and shares the common cation or common anion.

Complete answer:
Chemical compounds are classified into different types based on different bases. Salts are inorganic compounds that consist of both anion and cation. The cation in organic compound is other than proton \[\left( {{H^ + }} \right)\]and the anion is other than hydroxide \[\left( {O{H^ - }} \right)\]. Because any compound releasing a proton can be called an acid. The compound that can release hydroxide ions can be called as a base.
Mixed salt is one of the salt that contains two salts in a fixed proportion. This mixed salt shares either a common cation or common anion.
Some of the examples of mixed salts are bleaching powder, sodium potassium carbonate and calcium disodium EDTA. In which one mole of calcium and two moles of sodium for every mole of EDTA.
The bleaching powder has the formula of \[Ca{\left( {ClO} \right)_2}\] which is an example of mixed salt.

Note:
Mixed salt is the composition of two salts in a fixed composition and the double salt is also a salt in which the salt contains more than one cation or anion. One should not confuse double salt and mixed salt. Rochelle salt is an example of double salt.
