Question

A teacher is demonstrating osmosis by using egg but the egg has shell and she want to remove it

Answer 1

Answer:

Explanation:1-Place one egg in each glass. Pour in enough vinegar to cover each egg. Bubbles will start to form around the egg, and it’ll float up. To keep it submerged, put a butter knife in the glass to hold it down.

2-Put the three glasses in the refrigerator and allow to sit for 24 hours.

3-Gently holding the egg in the glass, pour out the old vinegar. Replace with fresh vinegar, and let sit in the refrigerator for another 24 hours. Repeat this process until the shells are fully dissolved and only the membrane remains. This should take about 2-3 days.

4- Gently remove the eggs using the slotted spoon and rinse with tap water in the sink. Rinse out the empty glasses as well.

5-Gently put the shell-less eggs aside for a moment on a plate.

6-*Prepare three different sugar-water solutions as follows, labeling with sticky notes:

• Glass 1: Label “hypertonic”. Pour in one cup of corn syrup.

• Glass 2: Label “isotonic”. Add 1 ½ tablespoons corn syrup to the one cup measuring cup, and fill the remainder with distilled water. Pour into glass (make sure you get all the corn syrup out!) and stir to dissolve.

• Glass 3: Label “hypotonic”. Pour in one cup of distilled water.Gently put one shell-less egg in each of the glasses, and let sit in the refrigerator for another 24 hours.
