Egg Osmosis and Chemical Reactions

The video tutorial demonstrates an experiment involving an egg, vinegar, corn syrup, and colored water. Initially, the eggshell dissolves in vinegar due to a chemical reaction, exposing the semi-permeable membrane. Water moves into the egg, causing it to swell. When placed in corn syrup, water exits the egg, leading to shrinkage. Finally, the egg rehydrates in colored water, swelling again as water moves back in.

What happens to the egg after being submerged in vinegar for 24 hours?

• The egg becomes smaller.

• The egg changes color.

• The egg shell dissolves, exposing the membrane.

• The egg becomes hard and solid.

What is the main component of vinegar that reacts with the eggshell?

• Hydrochloric acid

• Sulfuric acid

• Acetic acid

• Citric acid

What gas is produced when vinegar reacts with the eggshell?

• Nitrogen

• Hydrogen

• Oxygen

• Carbon dioxide

What characteristic of the egg membrane allows water to pass through?

• It is non-permeable.

• It is fully permeable.

• It is semi-permeable.

• It is impermeable.

Why does the egg swell when placed in vinegar?

• The egg absorbs water.

• The egg absorbs salt.

• The egg absorbs sugar.

• The egg absorbs air.

What happens to the egg when placed in corn syrup?

• It changes color.

• It becomes larger.

• It remains the same.

• It shrivels and shrinks.

Why does water leave the egg when it is in corn syrup?

• Because the egg has more electrolytes.

• Because the egg has more water molecules.

• Because the egg has more proteins.

• Because the egg has more sugar.

What is the main reason for the egg's change in size when placed in colored water?

• The egg absorbs electrolytes.

• The egg absorbs water.

• The egg absorbs sugar.

• The egg absorbs proteins.

What happens to the egg when placed in colored water after being in corn syrup?

• It swells again.

• It shrinks further.

• It changes color.

• It remains unchanged.

What is the main purpose of the egg osmosis experiment?

• To observe color changes in eggs.

• To understand the movement of water through membranes.

• To measure the weight of eggs.

• To test the strength of egg shells.
