[PoIsOngAlLeRy]

i rote bth too... p21 was easy enough..buh p5 seemed harder..

 

[KwameE]

hmm howd you guys decide to oxygenize the buffer solution?

 

[MuammarW]

that was the only question that left me confused at the end :S all i said is add a base,which will remove H ions which is oxidation OR pass a constant current of O2 gas..
