Using the knife, make a hole in each of the potatoes provided, put sodium chloride in the holes, and place the beaker containing distilled water. Let it stand for 30 minutes. Explain what happened.

After following the instructions and allowing the potatoes to sit for 30 minutes, the sodium chloride would have dissolved in the distilled water and created a saline solution. The potatoes would have absorbed some of this saline solution through the holes made with the knife.
As a result, the potatoes would have become slightly saltier and potentially more flavorful. The process of osmosis would have allowed the water and salt to move from an area of higher concentration (the saline solution) to an area of lower concentration (inside the potatoes), equalizing the concentration of salt on both sides of the potato membrane.
Overall, the potatoes would have undergone a slight change in taste and texture due to the absorption of the saline solution.

Materials:
- Knife
- Potatoes
- Sodium chloride (NaCl)
- Beakers
- Distilled water
Procedure:
1. Using the knife, make a small hole in each of the potatoes.
2. Place a small amount of sodium chloride in each of the holes.
3. Fill a beaker with distilled water.
4. Place the potatoes in the beaker of water.
5. Let the potatoes stand for 30 minutes.
Observations:
After 30 minutes, you will observe that the potatoes have become turgid and firm. The water level in the beaker will have decreased.
Explanation:
The process of osmosis occurred in this experiment. Osmosis is the movement of water molecules from an area of high concentration to an area of low concentration through a semipermeable membrane. In this experiment, the potato cells represent the semipermeable membrane. The distilled water represents the area of low concentration, and the sodium chloride solution inside the potatoes represents the area of high concentration.
When the potatoes were placed in the distilled water, water molecules moved from the distilled water into the potatoes through the semipermeable cell membranes. This influx of water caused the potatoes to become turgid and firm. The decrease in water level in the beaker is due to the water that moved into the potatoes.
The presence of sodium chloride in the potatoes increased the rate of osmosis. This is because the sodium chloride solution created a concentration gradient that favored the movement of water into the potatoes.
