Question

to observe diffusion across a semipermeable membrane, we will use dialysis tubing. what will be inside the dialysis tubing?
a) water
b) potassium iodide
c) glucose and starch
d) all of the above

Explanation:

In diffusion - across - semi - permeable membrane experiments using dialysis tubing, water, small molecules like potassium iodide, and mixtures such as glucose and starch can be placed inside to observe diffusion. Water can move by osmosis, potassium iodide can diffuse based on concentration gradients, and glucose (a small molecule) along with starch (a larger molecule to study size - based diffusion) can be used to study different aspects of diffusion.

Answer:

d) all of the above
