Question

These are lab questions, please answer with the best you can. I don't have much time to do the lab but I'm sure you can make up some numbers.

This lab will display the colligative properties of freezing point depression and osmotic pressure.

You'll need a few days and a few materials to complete this lab. Get your raw egg in a glass of vinegar to allow the shell to dissolve. You'll be making observations every 12 hours or so. When the shell has dissolved, put it in a glass with corn syrup and observe what happens.

Record your observations and answer the questions:

1. Data Table 1: Distilled water

2. Data Table 2: Salted Distilled water

4. Report the experimental freezing point for Distilled water and for Salted Distilled water below. Explain why these numbers are the same or different.

5. In the Osmotic Pressure portion of the lab, the egg should have changed after being submerged in corn syrup. Was the corn syrup hypotonic or hypertonic to the egg?

Hypotonic is when the concentration of the solution is lower than the cell system (egg in this case).
Hypertonic is when the concentration of the solution is higher than the cell system.

Explanation / Answer

The vinegar used in this experiment is just used to remove the outer white shell, during the removal of the shell some vinegar also seeps inside the egg, and hence makes it bigger than it was previously.

Data Table 3:

Initial Observations:

Time Lapsed: 0 hours Observations: Bubbles start appear on the outside of the egg.

Time Lapsed: 12 hours Observations: A white frothy scummy layer on the top of the surface of the vinegar.

Time Lapsed: 24 hours Observations: The white layer is gone and now the egg appears to be bigger in size.

Shell removed Observations:

Egg in corn syrup

Time Lapsed: 0 hours Observations: Size of the naked egg starts to shrivel up.

Time Lapsed: 12 hours Observations: The size of the egg is reduced to half, it seems that the water is going out of the egg.

Time Lapsed: 24 hours Observations: The egg is completely shriveled up, the egg is completely turned like a raisin.

Final Observations: Egg when placed in a vinegar solution losses up it's outer hard covering and also becomes large in size.But when the egg is placed into a solution of corn syrup, it losses it's water content and becomes dehydrated.

5. There are less solutes in the egg, so water will flow out of the egg into the corn syrup.
Hypertonic means there are more solute particles in the solution. In our experiment, the corn syrup is hypertonic because it contains more solute particles than the egg.
