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
|
london
|
|
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
|
saturated bc solid at room temp
|
|
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,
|
there are non polar sugars and starches
|
|
would extration be more or less effiecint if you extracted only one using 40 ml of petro ether or two 20ml extractions
|
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
|
|
what relationship doe you see between the apperance of the saponified fat and ph
|
lowr the ph the less soluble
|
|
why is it easier to seperate the saponified fatty acids from the aqueous reaction when the ph is more than for
|
bc fatty acids become protnated and lose charge
