Question

The hard shell of an egg is dissolved in acetic acid and then the egg was subsequently placed in saturated solution of NaCl

• A. The egg will shrink
• B. The egg will become harder
• C. The egg will swell
• D. No Change in the size of egg

Answer 1

The correct option is A

The egg will shrink

Molar concetration of solutes in a egg is less than the molar concentration of NaCl in a saturated solution. This is due to the very large molecular masses of the macromolecules present in the egg white or egg yellow. Due to lower concentration of solutes in egg, water will come out due to osmosis and egg will shrink.
