Question

describe the initial conditions. the tubing contains starch solution and lugols solution. the beaker contains

Explanation:

The tubing has a mixture of starch and Lugol's solution. Based on the context of diffusion - like experiments, the beaker likely contains a solution that can interact with the substances in the tubing. Usually, in such set - ups, the beaker contains only one of the substances to observe diffusion across a semi - permeable barrier (if present). Since the tubing has both, the beaker is likely to have only Lugol's solution to see if it diffuses into the tubing to react with starch.

Answer:

Lugol's solution
