Before you start this you should carefully read through the dialysis tubing lab procedure posted on Google Classroom. This assignment will be graded on correctness and you should complete it independently (not with anyone else). If you have questions please let me know!
Question 1

Which of the following is true about dialysis tubing?
Question 2

Question 4
4.
Which of the following is true about KI?
Question 5
5.
Which of the following is true about Benedict solution?
Question 6
6.
How high should you fill the beaker with water when you start the lab?
Question 7
7.
How much KI should you add to the beaker?
Question 8
8.
What should you add to the test tube without tape?
Question 9
9.
After you tie one end of the dialysis tubing how much should you fill it with starch/glucose solution using the dropper?
Question 10
10.
If there is a lot of extra tubing after you tie it off, what should you do?
Question 11
11.
Before you put the dialysis tubing "cell" inside of your beaker what should you do?
Question 12
12.
Which of the following is inside the dialysis tubing "cell" to start?
Question 13
13.
Which of the following is outside of the dialysis tubing "cell" to start (in the beaker)?
Question 14
14.
Should you stay in the lab space while you are waiting for the experiment to run?
Question 15
15.
Question 16
16.
Which data should you use to do your post lab?
It has large holes in it and will allow all molecules to move in and out of it
It will prevent small polar molecules from leaving or entering the cell because they are polar
It has small holes in it that will prevent smaller molecules from moving through it
Which of the following is true about starch?
It is made up of a bunch of glucoses bound together
It is a relatively large molecule (in comparison to glucose)
It is a relatively small molecule (in comparison to glucose)
When it is with KI the solution will turn dark purple
When it is with KI the solution will turn yellow
When it is heated and in the presence of Benedicts solution it will turn red/orange
When it is heated and in the presence of Benedicts solution it will turn blue
Which of the following is true about glucose?
It is made up of a bunch of glucoses bound together
It is a relatively large molecule (in comparison to starch)
It is a relatively small molecule (in comparison to starch)
When it is with KI the solution will turn dark purple
when it is with KI the solution will turn yellow
When it is heated and in the presence of Benedicts solution it will turn red/orange
When it is heated and in the presence of Benedicts solution it will turn blue
It turns dark purple in the presence of starch
It is a very large molecule
It turns dark purple in the presence of glucose
Once the experiment has run what should you do?
Write down the color inside of the cell
Write down the color outside of the cell
Pat down and weigh the cell
Calculate the change in mass of the cell
Throw away your cell
Dump the solution inside of your beaker/test tube without tape down the sink
Write your data on the board
Write down the color of the no tape test tube
Fill the tape test tube with the solution in the beaker and Benedict's solution and put it in the beaker on the hot plate
