Dialysis Tubing Pre-Lab

It is plastic

It will be used as an artificial cell

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

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

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 is a very small molecule

It turns yellow in the presence of starch

It turns dark purple in the presence of starch

It is a very large molecule

It turns dark purple in the presence of glucose

It turns red/orange when heated in the presence of starch

It turns dark purple when heated in the presence of starch

2 droppers full of Benedict's solution

3 droppers full of the KI solution from the beaker

3 drops of the KI solution from the beaker

2 drops of Benedict's solution

Throw the cell away

Weigh the cell and write down the mass

Write down the color of the inside of the "cell"

Write the color of the outside of the "cell"

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

Put the beaker/test tubes back at your station

Throw away the droppers
