Siqhubeka "nekhwalithi ephezulu, ukulethwa okusheshayo, intengo enamandla", sesisungule ukubambisana kwesikhathi eside nabathengi abavela kwamanye amazwe nasekhaya futhi sithola imibono emihle yamakhasimende amasha nawangaphambilini ngezithasiselo zokudla ze-Acetic acid, Samukela ngemfudumalo abangane abavela kuzo zonke izigaba zokuphila ukuze bafune ukubambisana futhi badale ikusasa elimangalisayo nelihle kakhulu.
Siqhubeka "nekhwalithi ephezulu, Ukulethwa Okusheshayo, Intengo Enamandla", sesisungule ukubambisana kwesikhathi eside nabathengi abavela kwamanye amazwe nasekhaya futhi sithola imibono emihle yamakhasimende amasha nawangaphambilini, Sibheke phambili, sizohambisana nesikhathi, siqhubeke nokudala imikhiqizo emisha. Ngethimba lethu eliqinile locwaningo, izikhungo zokukhiqiza ezithuthukisiwe, ukuphathwa kwesayensi kanye nezinsizakalo eziphezulu, sizohlinzeka ngemikhiqizo esezingeni eliphezulu kumakhasimende ethu emhlabeni jikelele. Sikumema ngobuqotho ukuthi nibe ngabalingani bethu bebhizinisi ukuze nizuze ndawonye.














Izithasiselo zokudla ze-Acetic acid Isixazululo se-Phenolphthalein indicator
Ncibilikisa i-1 g ye-phenolphthalein ku-100 mL ye-ethanol.
Inqubo yezithasiselo zokudla ze-acetic acid:
Kala u-2.5 g wesampula ngokunembile kuze kufike ku-0.0001 g ebhodleleni eliyindilinga elino-50 mL wamanzi angenayo i-carbon dioxide. Faka amaconsi amathathu esisombululo se-phenolphthalein indicator bese u-titrate ne-sodium hydroxide titrant (1 mol/L) kuze kuvele umbala opinki okhanyayo. I-1 mL ngayinye ye-sodium hydroxide titrant (1 mol/L) ilingana no-60.05 mg wezithasiselo zokudla ze-C₂H₄O₂.Acetic acid.
