Question

What ions are present in $ NaCl $ , $ N{a_2}C{O_3} $ , $ MgS{O_4} $ , and $ N{H_4}Cl $ $ ? $

Answer 1

Hint :Before starting writing the ions present in the given chemical compounds. Consider the formula to find the number of ions present in the chemical compounds.

Complete Step By Step Answer:
An ion is a small particle having an electrical charge. Ions are either single charged atoms known as simple ions or small charged molecules known as polyatomic ions. Examples of simple ions are $ N{a^ + } $ , $ C{l^ - } $ , etc. Examples of polyatomic ions are $ SO_4^{2 - } $ , $ CO_3^{2 - } $ and $ O{H^ - } $ .
The mathematical equation used to find the number of atoms, ions or molecules is $ N = n \times {N_A} $ .
Where $ N = $ number of particles in the compound or substance.
 $ n = $ amount of substance in moles (mol)
 $ {N_A} = $ Avogadro number $ = 6.022 \times {10^{23}} $ particles per mole.
The ions present in $ NaCl $ is one ion of sodium $ \left( {N{a^ + }} \right) $ and one ion of chlorine $ \left( {C{l^ - }} \right) $ .
Similarly, the ions present in $ N{a_2}C{O_3} $ is two ions of sodium $ \left( {N{a^ + }} \right) $ and one ion of carbonate $ \left( {C{O_3}} \right) $ with a charge of $ {2^ - } $ .
Similarly, the ions present in $ MgS{O_4} $ is one ion of magnesium $ \left( {M{g^{2 + }}} \right) $ and one ion of the sulphate $ \left( {SO_4^{2 - }} \right) $ .
Similarly, the ions present in $ N{H_4}Cl $ is one ion of ammonium $ \left( {N{H_4}^ + } \right) $ and one ion of the sulphate $ \left( {C{l^ - }} \right) $ .

Note :
Note that, in each chemical compound, the oppositely charged ions are held together by strong ionic bonds, and the molecules held together by strong intermolecular forces. Positively charged ions are called cations and negatively charged ions are called anions.
