Soda ya Caustic nimwe mubikoresho bikoreshwa cyane.Ikoreshwa mukutabuza aside;umunyu wa sodium ya tomake;kugusha ibyuma hydroxyde ya astheir;mu gutunganya peteroli;muri thesaponification ya esters;mu kuvura selulose, plastike, na rubber;no muri numeroussynthetic na analyse ya porogaramu.

Sodium hydroxide igurishwa mubucuruzi nka flake ya anhydrous cyangwa pellet cyangwa nkibisubizo byamazi 50% cyangwa 73%.Ifite inganda zitabarika zikoreshwa kandi nimwe mumiti 10 yambere mubijyanye numusaruro nogukoresha kurwego rwisi.Hafi ya toni miliyoni 15 za sodium hydroxide ikoreshwa buri mwaka.Ikoreshwa ryinshi, ritwara hafi kimwe cya kabiri cyumusaruro waryo, ni nkibanze mu gukora indi miti.Ikoreshwa mukugenzura pH no gutesha aside aside muburyo bwimiti.Inganda zimpapuro zikoresha cyane sodium hydoxide mugikorwa cya pulping.Sodium hydroxide ikoreshwa mugutandukanya fibre muguhagarika lignin ihuza.Ikoreshwa muburyo busa mukubyara rayon kuva selile.Sodium hydroxide ni imiti yingenzi mu nganda zamasabune.Mu nzira ya saponification, triglyceride ikomoka ku nyamaswa n’ibimera yashyutswe mu gisubizo kibi cyo gutanga glycerol nisabune:

Sodium hydroxide ikoreshwa mu nganda z’imyenda yo guhumanya no kuvura imyenda kugirango irangi ryoroshye.Inganda zikomoka kuri peteroli zikoresha hydroxide ya sodium mu gucukura ibyondo na asa bactericide.Sodium hypochlorite (NaOCl) ikoreshwa cyane mugusukura kandi nkumuti wica udukoko.Ibisanzwe byangiza urugo bigizwe na 5% sodium hypochlorite yumuti.Sodiumhypochlorite itegurwa no gukora chlorine hamwe na hydroxide ya sodium: Cl2 (g) + 2NaOH (aq) → NaOCl (aq) + NaCl (aq) + H2O (l).Sodium hydroxide ikoreshwa mu nganda zibiribwa mugusukura no gukuramo imbuto n'imboga.Sodium hydroxide ni ikintu gito mubicuruzwa bisanzwe bisanzwe, ariko muri bike birashobora kuba birenze kimwe cya kabiri cyibicuruzwa.Dranocrystal irimo hydroxide ya sodium iri hagati ya 30% na 60% kandi bamwe mubasukura imiyoboro irashobora kuba igizwe na hydroxide ya sodium 100%.
