*100ml of mineral oil was placed in to a homogenizer. Add 0.5 g of PVOH with phosphate buffer(prepared at part A) in to the homogenizer and homogenize it for 5 minutes. Pour it in to a beaker and place it in to a freezer at -20C for 20 hours.then thaw for 4 hours. 3 freeze-thaw cycle is required. | |||

ObjectiveDescription
Part A Synthesizing Phosphate Buffer
(Base/acid)=1.25.
Mass used for base: (119.98 g/mol)* 0.01115mol= 1.338g Mass used for acid: (141.96 g/mol) * 0.00885mol= 1.256g
Part B Dissolving PVOH with phosphate buffer
Part C
