Neutralization using hydrochloric acid is not typically done to the reaction mixture because it can potentially interfere with the desired chemical reaction taking place. Adding hydrochloric acid could disrupt the reaction conditions, alter the pH of the solution, or react with the reagents or products in unexpected ways. It is important to carefully control the reaction environment to ensure that the desired reaction proceeds efficiently and effectively, so introducing additional acid may not be beneficial and could even be harmful to the reaction outcome.
