Question

Calculate the number of electrons transferred when a solution containing 0.50 mol of HCl reacts with 0.50 mol of NaOH in a redox reaction.

Answer 1

Actually, the reaction between HCl and NaOH is not a redox reaction, but an acid-base reaction. In an acid-base reaction, there is no transfer of electrons, but rather a transfer of protons  H+ ions . The reaction between HCl and NaOH can be represented as follows:HCl  aq  + NaOH  aq   NaCl  aq  + H2O  l In this reaction, the H+ ion from HCl combines with the OH- ion from NaOH to form water  H2O , while the Na+ and Cl- ions form an ionic compound, sodium chloride  NaCl .Since this is not a redox reaction, there is no transfer of electrons involved.
