Explain the permeability of egg shell in different solutions.
Answers
Answer:
After dissolving the eggshell, we are left with a membrane that holds the insides of the egg. This membrane is selectively permeable. This means that it lets some molecules move through it and blocks out other molecules. ... This is because the vinegar has a higher concentration of water than the inside of the egg.

Hope its help you
Explanation:
After dissolving the eggshell, we are left with a membrane that holds the insides of the egg. This membrane is selectively permeable. This means that it lets some molecules move through it and blocks out other molecules. Water moves through the membrane easily. Bigger molecules, like the sugar molecules in the corn syrup, do not pass through the membrane.
You may have noticed that the egg expanded in the initial vinegar solution when you dissolved the shell. This is because the vinegar has a higher concentration of water than the inside of the egg.
To reach equilibrium, water molecules move from the vinegar into the egg through the semi-permeable membrane. If the membrane were completely permeable, water molecules would move in and protein would move out until both solutions were the same concentration. Since the egg membrane is semi-permeable, water can move in but proteins cannot move out.
