Sihlala sisenza “umgangatho ophezulu, ukuhanjiswa ngokukhawuleza, ixabiso elibukhali”, siqalise intsebenziswano yexesha elide nabathengi abavela kwamanye amazwe nasekhaya kwaye sifumana izimvo eziphezulu zabathengi abatsha nabangaphambili malunga nezongezo zokutya ze-Acetic acid, Siyabamkela ngokufudumeleyo abahlobo abavela kuzo zonke iinkalo zobomi ukuze bafune intsebenziswano efanayo kwaye benze ikamva elimangalisayo nelimangalisayo.
Siqhubeka "nomgangatho ophezulu, ukuhanjiswa ngokukhawuleza, ixabiso elinobundlongondlongo", siseke intsebenziswano yexesha elide nabathengi abavela kwamanye amazwe nasekhaya kwaye sifumana izimvo eziphezulu zabathengi abatsha nabangaphambili, Sijonge phambili, siza kuhambelana namaxesha, siqhubeka nokwenza iimveliso ezintsha. Ngeqela lethu elinamandla lophando, izibonelelo zemveliso eziphambili, ulawulo lwesayensi kunye neenkonzo eziphambili, siza kubonelela abathengi bethu ngemveliso esemgangathweni ophezulu kwihlabathi liphela. Siyanimema ngokunyanisekileyo ukuba nibe ngamaqabane ethu oshishino ukuze kubekho iingenelo ezifanayo.














Izongezo zokutya ze-acetic acid Isisombululo se-Phenolphthalein indicator
Nyibilikisa i-1 g ye-phenolphthalein kwi-100 mL ye-ethanol.
Inkqubo yezongezo zokutya ze-acetic acid:
Bula i-2.5 g yesampulu ngokuchanekileyo ukuya kwi-0.0001 g kwiflaski evaliweyo equlethe i-50 mL yamanzi angenayo i-carbon dioxide. Yongeza amathontsi ama-3 esisombululo se-phenolphthalein indicator uze u-titrate kunye ne-sodium hydroxide titrant (1 mol/L) ude kuvele umbala opinki ocacileyo. I-1 mL nganye ye-sodium hydroxide titrant (1 mol/L) ilingana ne-60.05 mg ye-C₂H₄O₂.Acetic acid izongezo zokutya.
