Faʻamatalaga puʻupuʻu:

O le autu mafuaʻaga o le copper sulfate o se suʻesuʻega auiliili, mo se faʻataʻitaʻiga, e mafai ona faʻaaogaina i le biology e faʻatulaga ai le Fehling reagent mo le faʻailoaina o le faʻaititia o suka ma le B vai o le biuret reagent mo le faʻailoaina o polotini, ae e masani ona faʻaaoga nei;
Faʻaaogaina o se meaʻai-vasega chelating sooupu ma le faʻamalamalamaina sooupu, faʻaaogaina i le gaosiga o gaioiga o faʻasao fuamoa ma le uaina; i le matata alamanuia. Faʻaaogaina i le gaosiaina o isi masima 'apamemea pei o cuprous chloride, cuprous chloride,' apamemea pyrophosphate, cuprous oxide, 'apamemea acetate,' apamemea carbonate, 'apamemea monoazo vali e pei o le toe malosi o le lanumoana pupula, o le violet malosi
