Answer 2

Answer :

(1) The name of $Al_2(SO_4)_3$ is, Aluminium sulfate

(2) The name of $CaCl_2$ is, Calcium chloride

(3) The name of $K_2SO_4$ is, Potassium sulfate

(6) The name of $NH_4Cl$ is, Ammonium chloride

Explanation :

The given compounds are the ionic compounds.

ionic compound : These are the compounds in which atoms are bonded through ionic bond.  

Ionic bonds are formed by the complete transfer of electrons. The atom which looses the electron is considered as electropositive atom and the atom which gains the electron is known as electronegative atom.

These bonds are formed between one metal and one non-metal.

The nomenclature of ionic compounds is given by :

• Positive cation is written first.
• The negative anion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
