Citronsyre (800 g)
Eddikesyre 99-100% p.a. (1 liter)
189,00 kr.
Natriumhydroxid, fast (1 kg)
89,00 kr.
Natriumhydroxid i teknisk ren kvalitet (> 99 % NaOH)
Kornstørrelsen er mikroperler, der kan sammenlignes med køkkensalt i strukturen, og gør det meget let at opløse og fremstille natriumhydroxidopløsninger.
Til 4 molær NaOH-opløsning opløses 160 g NaOH (s) i 1 liter vand (demineraliseret eller destilleret).
Til 1 molær NaOH opløsning opløses 40 g fast NaOH i 1 liter vand.
OBS: Stærkt hudætsende og metalætsende, og bør kun håndteres af læreren.
CAS: 1310-73-2
Synonymer: Kaustisk soda
