I-Caustic soda ingelinye lamakhemikhali asetshenziswa kakhulu.Isetshenziselwa ukunciphisa ama-acids;ukwenza usawoti we-sodium;ukusheshisa izinsimbi astheir hydroxides;ekucwengisweni kwe-petroleum;ekufakweni kwe-esters;ekwelapheni i-cellulose, ipulasitiki, nerabha;kanye nezinhlelo zokusebenza eziningi zokwenziwa nezokuhlaziya.

I-sodium hydroxide ithengiswa ngokuthengisa njengama-anhydrous flakes noma ama-pellets noma njenge-50% noma i-73% yezixazululo ezinamanzi.Inemisebenzi eminingi yezimboni futhi ingelinye lamakhemikhali ayi-10 aphezulu mayelana nokukhiqizwa nokusetshenziswa emhlabeni jikelele.Kusetshenziswa amathani ayizigidi eziyi-15 e-sodium hydroxide ngonyaka.Ukusetshenziswa kwayo okukhulu kakhulu, kudla cishe ingxenye yokukhiqizwa kwayo, kuyisisekelo sokukhiqiza amanye amakhemikhali.Isetshenziselwa ukulawula i-pH futhi inciphise ama-asidi ezinqubweni zamakhemikhali.Imboni yephepha isebenzisa kakhulu i-sodium hydroxide enqubweni yokudonsa.I-sodium hydroxide isetshenziselwa ukuhlukanisa imicu ngokuhlakaza i-lignin yokuxhuma.Isetshenziswa ngendlela efanayo ekukhiqizeni i-rayon kusuka ku-cellulose.I-sodium hydroxide iyikhemikhali eyinhloko embonini yensipho.Enqubweni ye-saponification, ama-triglycerides atholakala esilwaneni nasezitshalweni ashiswa ngesisombululo se-abasic ukunikeza i-glycerol nensipho:

I-sodium hydroxide isetshenziswa embonini yendwangu ukwenza bleaching kanye nokwelapha izindwangu ukuze kwenziwe ukudaya kube lula.Imboni ye-petroleum isebenzisa i-sodium hydroxide ekumba amadaka kanye ne-asa bactericide.I-sodium hypochlorite (NaOCl) isetshenziswa kakhulu ekuhlanzeni nanjengesibulala-magciwane.I-bleach evamile yasendlini iqukethe cishe u-5% we-sodium hypochlorite solution.I-Sodiumhypochlorite ilungiswa ngokuphendula i-chlorine ne-sodium hydroxide: Cl2(g) + 2NaOH(aq) →NaOCl(aq) + NaCl(aq) + H2O(l).I-sodium hydroxide isetshenziswa embonini yokudla ukuhlanza nokuxebula izithelo nemifino.I-sodium hydroxide iyisithako esincane emikhiqizweni eminingi evamile, kodwa kwembalwa ingase yakhe ngaphezu kwengxenye yomkhiqizo.Ama-dranocrystals aqukethe phakathi kuka-30% no-60% we-sodium hydroxide kanti amanye ama-drano cleaners angaba no-100% we-sodium hydroxide.
