Question

1. students investigate osmosis using dialysis tubing. dialysis tubing is a semipermeable membrane that allows water molecules to pass through while preventing salt ions from passing through. the students follow this procedure: 1. mix salt into water to make a 7.1% salt solution. 2. add equal amounts of this saltwater solution to four small bags made of dialysis tubing. 3. fill four beakers with different salt solutions, as shown in the image below. 4. place each small bag into one of the four beakers. 5. observe changes in the size of the bags. the setup for the investigation is shown below. in which beaker will osmosis cause the dialysis tube to gain mass? beaker 1: 5.4% salt solution beaker 2: 7.1% salt solution beaker 3: 9.3% salt solution beaker 4: 11.2% salt solution options: beaker 1, beaker 2, beaker 3, beaker 4

Explanation:

Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to higher solute concentration. For the dialysis tube to gain mass, water must move into it. This happens when the solution inside the tube (7.1% salt) has a higher solute concentration than the beaker's solution, meaning the beaker has a lower salt concentration.

Answer:

Beaker 1. 5.4% salt solution
