Question

a dialysis tube with a 10% internal salt concentration is put in a beaker of 10% salt water. the beaker is a(n) __________ environment, and the mass of the dialysis tube will __________.

Explanation:

Step1: Understand tonicity concepts

Tonicity is related to solute - concentration differences. Isotonic solutions have equal solute concentrations.

Step2: Analyze the situation

The dialysis tube has 10% salt and the beaker has 10% salt. Since the salt - concentration inside the dialysis tube and in the beaker is the same, there is no net movement of water by osmosis.

Answer:

isotonic, stay the same
