Sodium hydroxide (NaOH), inozivikanwawo se caustic soda ,lye uye Piece yealkali, inorganic compound.Iyo chena yakasimba uye yakanyanya caustic metallic base uye alkali munyu wesodium iyo inowanikwa mumapellets, flakes, granules, uye semhinduro dzakagadzirirwa pane akati wandei akasiyana.Sodium hydro xide inoumba inenge 50% (kuburikidza nehuremu) yakazara mhinduro nemvura.;Sodium hy droxide inonyungudika mumvura, ethanol, uye ini thanol.Alkali iyi inonetsa uye inotora hunyoro necarbon dioxide mumhepo.
Sodium hyd roxide inoshandiswa mumaindasitiri mazhinji, kunyanya sechinhu chakasimba chemakemikari base mukugadzira pulp nebepa, machira, mvura yekunwa, sipo uye detergents uye sedhivha yekuchenesa.
