ObjectiveDescriptionPart A: pH study *HCl solutions with different pH were prepared( pH 1.5, 2.5 & 3.5) in order to mimic the pH of stomach. Each hydrogels were left in the solution until wednesday.
1)PVOH (MW:146,000) with R6G (prepared on 30/01/2013)=0.22g 2)PVOH (MW:130,000) with R6G (prepared on 30/01/2013)=0.66g 3)PVOH (MW:89,000-98,000) with (prepared on 30/01/2013)=0.55g DataObservation 1: PVOH with 22,000 molecular mass was still liquid after 3 cycles therefore it can be concluded that it might not be a good candidate for this research.
MW= 22,000g/mol(it was still liquid.) MW=89,000 g/mol (most homogeneous hydrogel) MW=130,000 g/mol (It was not homogenous. undissolved solids were visible in the hydrogel) MW=146,000 g/mol (it was not homogenous. visible undissolved solids were present) Notes
