Detailed explanation-1: -Answer. Answer: An egg with a dissolved shell is placed in pure water for 48 hours. Water will move in and out of the cell equally, and the cell with neither shrink nor swell.
Detailed explanation-2: -This process of water moving through a membrane is called osmosis. Osmosis equalizes – or makes the concentration of water on both sides of the egg membrane the same. This means the egg will swell as the water moves inside and get larger.
Detailed explanation-3: -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.
Detailed explanation-4: -Giving large amounts of pure water directly into a vein would cause your blood cells to become hypotonic, possibly leading to death.
