Sodium hydroxide (NaOH), izwi kandi nka caustic soda, lye na Piece ya alkali, ni uruganda rudasanzwe.Nibintu byera byera kandi byitwa caustic metallic base hamwe numunyu wa alkali wa sodium iboneka muri pellet, flake, granules, kandi nkibisubizo byateguwe muburyo butandukanye.Sodium hydro xide ikora hafi 50% (kuburemere) igisubizo cyuzuye n'amazi.;Sodium hy droxide irashonga mumazi, Ethanol, na me thanol.Iyi alkali iratanga kandi igahita ikuramo ubuhehere na dioxyde de carbone mu kirere.
Sodium hyd roxide ikoreshwa mu nganda nyinshi, cyane cyane nk'ishingiro rikomeye ry’imiti mu gukora impapuro nimpapuro, imyenda, amazi yo kunywa, amasabune hamwe nogusukura ndetse nogusukura amazi.
