Folasaga
O le 2-Bromo-5-nitrobenzoic acid o se vailaʻau faʻalaʻau ma le fua faʻasolosolo C7H4BrNO4. O lo'o taua i lalo se fa'amatalaga o lona natura, fa'aoga, sauniuniga ma fa'amatalaga saogalemu:
natura:
- 2-Bromo-5-nitrobenzoic acid o se tioata malo samasama, leai se manogi.
-E le mafai ona solu i le vai i le vevela o le potu, ae soluble i solvents organic pei ole ethanol, chloroform ma dimethyl sulfoxide.
-O loʻo i ai se tulaga faʻapitoa o le mautu, ae e mafai ona tali atu i le i ai o oxidants malosi.
Fa'aaogā:
- 2-Bromo-5-nitrobenzoic acid e masani ona faʻaaogaina e avea o se mea taua tele i le faʻaogaina o meaola.
-E mafai ona tali atu i isi mea fa'apipi'i e fa'atupu ai fa'aputuga fou.
-E mafai foi ona faʻaaogaina e saunia ai lanu felanulanuaʻi, vailaʻau faʻamaʻi ma vailaʻau vailaʻau.
Metotia:
- 2-Bromo-5-nitrobenzoic acid e mafai ona saunia i laasaga nei:
1. fa'afefete le vaila'au benzoic ma le acid nitric concentrated e maua ai le nitrobenzoic acid.
2. fa'aopoopoina le bromine e tali atu i le nitrobenzoic acid i lalo o tulaga talafeagai e maua ai le 2-Bromo-5-nitrobenzoic acid.
Fa'amatalaga Saogalemu:
- 2-Bromo-5-nitrobenzoic acid o se faʻalapotopotoga faʻapitoa, ma e tatau ona gauai atu i lona oona.
-I le taotoga, e tatau ona fai matatioata puipui ma totigilima, aloese mai le paʻu o le paʻu.
- Fa'agaoioi i totonu o se si'osi'omaga fa'alelei lelei e 'alofia ai le manavaina o le pefu po'o le kesi mai le mea.
-Afai o le soona inu o le vailaʻau e faʻaaoga i se mea sese pe manava, faʻafesoʻotaʻi vave se fomaʻi ma faʻailoa i le fomaʻi le tulaga.
- Taofi mai le afi ma le vevela ma teu i se nofoaga malulu ma matutu.
