FeSO4(aq) + K3PO4 (aq) —&gt;
ch4aika [34]

An ionic equation is a chemical equation in which the electrolytes in aqueous solution are described as dissociated ions.

<h3>What is the difference between ionic equation and net ionic equation?</h3>
  • A complete ionic equation also contains the spectator ions, whereas a net ionic equation just displays the chemical species that are involved in a reaction.
  • A molecular formula has two or more atoms bonded together, whereas a chemical formula can only refer to one atom. They are both elements, and their chemical symbols are unchanged.
  • An ionic equation is a chemical equation in which the electrolytes in aqueous solution are described as dissociated ions. It is similar to a molecular equation in that it expresses compounds as molecules.

3FeSO4(aq) + 2K3PO4(aq) = Fe3(PO4)2(s) + 3K2SO4(aq)

ionic equation : 3Fe(2+)(aq) + 3SO4(2-)(aq)+ 6Na(+)(aq) + 2PO4 (3-) (aq) → Fe3(PO4)2(s)+ 6Na(+) + 3SO4(2-)(aq)

net ionic equation: 3Fe(2+)(aq)  + 2PO4 (3-)(aq) → Fe3(PO4)2(s)  

K2CO3(aq) + CdI2(aq) = 2KI(aq) + CdCO3(s)

net ionic equation for K2CO3(aq) + CdI2(aq) = 2KI(aq) + CdCO3(s).

2HNO3 + CaCO3 = Ca(NO3)2 + H2O + CO2

ionic equation :  CaCO3(s) + 2H+(aq) → Ca2+(aq) + CO2(g) + H2O()
