* Neutralization Reaction: The reaction between HCl (a strong acid) and NaOH (a strong base) is a neutralization reaction. The equation is:
HCl (aq) + NaOH (aq) → NaCl (aq) + H₂O (l)
* Consumption of Reactants: The reaction consumes both HCl and NaOH, converting them into sodium chloride (NaCl) and water (H₂O).
* Decreasing HCl Concentration: As the reaction progresses, the amount of HCl in the solution decreases, leading to a lower concentration.
* Complete Neutralization: When the reaction reaches a point where all the HCl has reacted with NaOH, the solution is said to be neutralized. At this point, the concentration of HCl would be effectively zero.
Important Note: The final concentration of the solution depends on the initial concentrations of HCl and NaOH and the stoichiometry of the reaction.
