Modify: 2024-04-16. Description. At room temperature, sodium hydroxide is a white crystalline odorless solid that absorbs moisture from the air. It is a manufactured substance. When dissolved in water or neutralized with acid it liberates substantial heat, which may be sufficient to ignite combustible materials.
Reaction with acids. Sodium hydroxide reacts with protic acids to produce water and the corresponding salts. For example, when sodium hydroxide reacts with hydrochloric acid, sodium chloride is formed: NaOH(aq) + HCl(aq) → NaCl(aq) + H 2 O(l) In general, such neutralization reactions are represented by one simple net ionic equation:
- NaOH
- 39.9971 g/mol
- 323 °C (613 °F; 596 K)
- 418 g/L (0 °C), 1000 g/L (25 °C), 3370 g/L (100 °C)

Sep 16, 2022 · Acids and Bases React with Metals. Acids react with most metals to form a salt and hydrogen gas. As discussed previously, metals that are more active than acids can undergo a single displacement reaction. For example, zinc metal reacts with hydrochloric acid, producing zinc chloride and hydrogen gas. Zn(s) + 2HCl(aq) → ZnCl2(aq) +H2(g) Zn ( s ...
Jul 12, 2019 · For example, sodium acetate, NaCH 3 CO 2, is a salt formed by the reaction of the weak acid acetic acid with the strong base sodium hydroxide: \[\ce{CH3CO2H}(aq)+\ce{NaOH}(aq) \ce{NaCH3CO2}(aq)+\ce{H2O}(aq) onumber \] A solution of this salt contains sodium ions and acetate ions. The sodium ion has no effect on the acidity of the solution.
Jun 30, 2023 · An equation can be used to describe a physical reaction, which involves a change of states. For example, melting, sublimation, evaporation, and condensation can be represented as follows. In these equations, (s) stands for solid, (l) for liquid (l), and (g) for gas. melting: H2O(s) → H2O(l)
