Predict Question 1: What effect will increasing the pore size of the filter have on the filtration rate? Your answer: The filtration rate will increase.
1
Predict Question 2: What will happen if you increase the pressure above the beaker (the driving pressure)? Your answer: The filtration rate will increase.
2
The reason none of the solutes were present in the filtrate was that You correctly answered: the solutes were all too large to pass through.
