Case Study 1

Use the following information and the graph on next slide to answer questions 1-3. The graph shows dialysis bags (each bag is a semi-permeable membrane which is permeable to water and they each contain concentration at the start of the experiment) placed into different solutions each of unknown solute. It represents change in mass over time ending at 25 minutes. 

Multiple Choice

What is the tonicity of Solution A relative to the solution in the dialysis bag?

• hypertonic

• hypotonic

• isotonic

• More information is needed to answer the question

Multiple Choice

What is the tonicity of Solution B relative to the solution in the dialysis bag?

• hypertonic

• hypotonic

• isotonic

• More information is needed to answer the question.

Multiple Choice

What is the tonicity of Solution C relative to the solution in the dialysis bag?

• Hypertonic

• Hypotonic

• Isotonic

• More information is needed
