what happens when sodium hydroxide reacts with dilute hydrochloric acid

Sodium Hydroxide reacts with dilute hydrochloric acid it forms salt and water hope it helps you thank you
What happens when hydrochloric acid and sodium hydroxide are mixed together?
The result is the formation of ordinary table salt, sodium chloride and an equimolar amount of water. This reaction also gives off significant heat that could conceivably cause the reaction mixture to explosively boil.
This is the reaction:
NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l)
While I don’t have the deltaG, deltaH or S of this reaction, I know from personal experience that its quite exothermic, meaning the solution will get quite hot. If the reactants are sufficiently concentrated, the reaction could explosively boil, so if you feel you must react concentrated reagents, do the addition very slowly, preferably base to acid.
NEVER combine these too reactants quickly, especially if they’re concentrated, or else you may be seriously scalded by steam and boiling droplets of water, and possibly cut up by hot broken bits of glass from the exploded reaction vessel.
Technically, especially if the chemist is very precise with an equimolar (meaning exactly the same amount of HCl and NaOH) reaction, the result should be neutral pH salt-water. Theoretically, it would be no worse than drinking ordinary water with some table salt (NaCl) dissolved in it, if you drank the end product of this reaction (take the pH first just to be on the safe side—look for a 6–8 and ideally 7). This is assuming you have used reagent-grade or better purity reactants. If not reagent-grade, the stuff won’t kill you nor likely make you sick, but it may not taste as pleasant as ordinary salt-water. While the reaction should be complete almost immediately, I would suggest you let it cool a while first before taking a sip!!
As a note of caution, you should never do more than a small taste of a reaction like this, unless your supervisor, professor, etc., says it’s okay to do so. So, it’s better to err on the side of caution. Even knowing what I know about chemistry, I still don’t do more than a taste of a supposedly safe product from a reaction I’ve performed, and almost invariably spit out the taste. Even if I’m 99.9% sure it’s perfectly fine, its that 0.1% that can still get you. Better safe than sorry.
