Final answer:
Vinegar, which is an acid solution, can dissolve the eggshell and make it more flexible. When the egg is placed in syrup, water moves out of the egg due to osmosis. Unlike animal cells, plant cells do not explode when they fill with water because of their cell wall. The use of salt on roadways during winter months can have negative consequences for organisms near those roadways.
Step-by-step explanation:
a. What effect did the acetic acid have on your egg?
Acetic acid in vinegar can dissolve the eggshell, causing it to soften and become more flexible. This is because acetic acid is an acid and can react with the calcium carbonate in the eggshell.
b. What effect did the water have on your egg?
Water in vinegar does not have a direct effect on the egg. However, water acts as a solvent and helps to dilute the acetic acid in vinegar.
c. What kind of solution is vinegar in relation to the egg?
Vinegar is an acid solution in relation to the egg.
2. What happened when the egg was placed in syrup?
When the egg is placed in syrup, water molecules move out of the egg into the syrup due to osmosis. This happens because the syrup has a higher concentration of solute than the egg.
a. What kind of solution is the corn syrup in relation to the egg?
Corn syrup is a hypertonic solution in relation to the egg, meaning it has a higher concentration of solute than the egg.
3. Unlike animal cells, plant cells will not explode when they fill with water because of their cell wall; instead, they become turgid or rigid. Knowing this, why do you think grocery stores install sprayers over the vegetables?
Grocery stores install sprayers over the vegetables to provide water and keep them hydrated. This helps maintain the turgidity of plant cells and keeps the vegetables looking fresh.
4. Salt will have a similar effect on water balance as sugar, it is also very effective in melting ice and is commonly used on roadways during the winter months. If salt is used to improve winter driving conditions, what are the potential consequences for the organisms that exist near those roadways?
The use of salt on roadways during winter months can have negative consequences for the organisms near those roadways as salt can runoff into nearby water sources. This high concentration of salt in water can be harmful to aquatic organisms and plants, affecting their health and survival.
Conclusion
The purpose of this lab was to understand the effects of different solutions on biological systems such as eggs and plant cells. From this lab, we learned that different concentrations of solutions can have varying effects on living organisms, and that understanding the principles of solute concentration and osmosis is important in many biological processes.
