Question

Write the reaction equation with line structures for the following reactions:

NaCl + H2O-->

NaCl + Et2O-->

NaCl + HCl-->

NaCl + NaOH -->

NaCl + NaHCO3-->

Answer 1

The equation is

NaCl + H₂O = NaOH + HCl

NaCl + Et₂O = no reaction

Nacl is salt which is soluble in water but insoluble in organic solvent. Et₂O is an organic solvent and can not dissolve NaCl. So NaCl can not react with it.

NaCl + HCl = no reaction

2 ionic compound will react if they contain different cation and anion. Here they have different cation [Na⁺ and H⁺] but have same anion [Cl^-]

NaCl + NaOH = no reaction

Here also they have same cation Na⁺ ,so they do not react.

NaCl + NaHCO₃ = no reaction due to similar reason of above case.

These reacts do not occur. They only ionised and no ultimate reaction occurs.

NaCl + HCl = Na⁺ + Cl^- + H⁺ + Cl^-

NaCl + NaOH = Na⁺ + Cl^- + Na⁺ + OH^-

NaCl + NaHCO₃ = Na⁺ + Cl^- + Na⁺ + HCO₃^-
