Autor: Miqdaam Hamed Hassan



Respuesta:

1)Use a pipette to transfer 25cm3 sodium hydroxide soloution to a conical flask. Dont blow liquid out, let it drain out to avoid an incorrect volume 2)Add 5 drops of indicator (methyl orange) to alkali in conical flask 3)Place flask on white tile 4)Fill a buirette with sulfuric acid. Then begin adding it into the flask and swirl. 5)Once colour begins changing, add drop by drop until neutral (yellow to red) 6)Read buirette volume at bottom of meniscus 7)Repeat titration untill you get 2 results withing 0.1 cm3, take a mean for final volume.
