Question

to observe diffusion across a semipermeable membrane, we will use dialysis tubing. what will be in the beaker outside the dialysis tubing?

a) water and potassium iodide
b) starch
c) glucose
d) all of the above

Explanation:

In diffusion experiments using dialysis tubing, water and small - sized molecules like potassium iodide can be placed outside. Starch is a large molecule and glucose is a small molecule. Typically, water and a small - molecule indicator like potassium iodide are in the beaker outside to observe diffusion across the semi - permeable membrane.

Answer:

a) Water and potassium iodide
