HCl is in almost all cases already aqueous for common chemistry, mostly dissociated into $\ce{H^+} + \ce{Cl^-}$ because it is a strong acid, which means water is the primary solvent, not HCl. As a result, when mixed with HCl (acid) it will react to form salt and water, both neutral substances. For example, pure water is neutral (pH of 7). In the meantime, to ensure continued support, we are displaying the site without styles JAMA 206, 591595 (1968). Filling the burette, measuring out the alkali into the flask, and titrating it until it is neutralised takes about 20 minutes, with false starts being likely for many groups. Noinaj, N. et al. However, it is also important to consider the number of hydrogen bonds formed between molecules, as you have already noted in your question. In chemistry, neutral means not being an acid or a base. Well look at our planet from a distance. Despite the aggression of the sodium hydroxide and hydrochloric acid, the reaction was a wonderful one.
