Experiment 11

Front 1

you extracted fat using petroleum ether becaues fat is higly soulble in petro ether. whicy type of intermolecular forces is liely to be dominated between fat molecules and petro ether

Back 1

london

Front 2

the fat you extracted is a mixture of many triglyercides, some saturated and some unsaturated. what does the appearance of the extractef at tell you aout the chemical structure of these triglycerides

Back 2

saturated bc solid at room temp

Front 3

fat is cololess, tasteless and oderless. this experiment assumes that fat is the only nonpolar substance int he chips, do you see any evedient that this assumption is valid,

Back 3

there are non polar sugars and starches

Front 4

would extration be more or less effiecint if you extracted only one using 40 ml of petro ether or two 20ml extractions

Back 4

2, becuse the ratio of concentrations of a compound in the two phases of a mixture of two immiscible solvents at equilibrium.[1] Hence these coefficients are a measure of differential solubility of the compound between these two solvents. more accurate due to this

Front 5

what relationship doe you see between the apperance of the saponified fat and ph

Back 5

lowr the ph the less soluble

Front 6

why is it easier to seperate the saponified fatty acids from the aqueous reaction when the ph is more than for

Back 6

bc fatty acids become protnated and lose charge
