Hydrochloric acid (HCl), a strong acid, is composed of a single hydrogen atom and a single chlorine atom bonded together covalently. This means that your reactants will be sodium metal and hydrochloric acid, since these are the substances that are being transformed to form salt and hydrogen gas. Comprehensive molecular portraits of invasive lobular breast. These authors contributed equally: Anne E. Carlisle, Namgyu Lee.

In order to neutralize hydrochloric acid with sodium hydroxide, the following steps must be followed: Neutralization reactions are classified as exothermic reactions. Learn how to neutralize hydrochloric acid. As we can see, the result of the interaction of two highly aggressive compounds is table salt and water - compounds that are ultimately harmless, even beneficial, to human beings. On this Wikipedia the language links are at the top of the page across from the article title. Once we are almost finished adding the 2.5 L of sodium hydroxide, we start checking the pH.
