    Sodium hydroxide (NaOH), tseem hu ua caustic soda, lye thiab Piece of alkali, yog ib qho inorganic compound.Nws yog ib qho khoom siv dawb thiab ua rau lub hauv paus muaj zog thiab alkali ntsev ntawm sodium uas muaj nyob rau hauv pellets, flakes, granules, thiab raws li npaj cov kev daws teeb meem ntawm ntau qhov sib txawv.Sodium hydro xide tsim ib qho kwv yees li 50% (los ntawm qhov hnyav) saturated tov nrog dej.Sodium hydroxide yog soluble hauv dej, ethanol, thiab me thanol.Qhov no alkali yog deliquescent thiab nkag tau yooj yim absorbs noo noo thiab carbon dioxide nyob rau hauv cov huab cua.

    Sodium hyd roxide yog siv nyob rau hauv ntau qhov kev lag luam, feem ntau yog cov tshuaj muaj zog hauv kev tsim cov ntawv thiab ntawv, textiles, dej haus, xab npum thiab detergents thiab ua cov dej huv.
