Vinegar is a homogeneous solution because it is a perfectly uniform solution of liquid in liquid (acetic acid in water)
2) The control group was the egg in vinegar, which is the isotonic solution.
Occasionally even the egg breaks in the hypotonic solution. By soaking the eggs in vinegar, the eggshell will dissolve and the whites will become gummy. (due to a chemical reaction) Water can therefore flow in and out of the egg.
Hypotonic saline, i. H. 0.45% sodium chloride or 0.25% sodium chloride with or without dextrose, 2.5% dextrose solution etc. are some of the examples of hypotonic solutions which are hypotonic in relation to blood serum and are called hypotonic intravenous solutions used.
A solution is hypertonic for a cell if its concentration of solutes is higher than that inside the cell and the solutes cannot cross the membrane.
When comparing two solutions with unequal solute concentrations, the solution with the higher solute concentration is hypertonic and the solution with the lower solute concentration is hypotonic.
Tap water and plain water are hypotonic. A single animal cell (like a red blood cell) placed in a hypotonic solution will fill with water and then burst.
A solution is isotonic if its effective molar concentration is the same as that of another solution. This condition allows for the free movement of water across the membrane without changing the concentration of solutes on either side. Some examples of isotonic solutions are 0.9% normal saline and Lactated Ringer.
The solution in the egg membrane contains a complex solution of salts, proteins, lipids and carbohydrates. Compared to distilled water, the solution in the egg shell is hypertonic.
When you soak an egg in vinegar the eggshell absorbs the acid and breaks down or dissolves. The calcium carbonate becomes carbon dioxide gas, which becomes airborne. What’s left is the soft tissue that lines the inside of the eggshell. It will bounce!
You may have noticed that the egg expanded in the initial vinegar solution as you dissolved the shell. This is because the vinegar has a higher concentration of water than the inside of the egg. To achieve equilibrium, water molecules migrate from the vinegar into the egg through the semi-permeable membrane.
Hypertonic solutions have a higher concentration of dissolved particles than blood. An example of a hypertonic IV solution is 3% normal saline (3% NaCl). When infused, hypertonic fluids cause an increased concentration of solutes in the intravascular space compared to the cells.
For example, a solution containing 10% salt is hypertonic. When a cell is placed in a hypertonic environment, there is a net movement of water to the outside of the cell (from the higher water environment inside the cell). In response, the cell shrinks. A solution with a low concentration of solutes is called hypotonic.
Hypotonic solutions have lower concentrations of solutes like salt and electrolytes than the cells they contain. Water from the solution crosses the cell membrane and enters the cell. You will find hypotonic solutions in the laboratory, in the hospital and in your everyday life.
Seawater. Seawater has a high amount of salt particles compared to freshwater, making it a hypertonic solution. Freshwater fish cannot live in seawater because the water would flow out of their cells into the surrounding salt water. They would soon die of dehydration.
So FeCl3 is hypertonic.
Isotonic solutions are most commonly used for regular maintenance of clean, healthy sinuses – a soothing wash to remove excess mucus, dust and allergens – and for treating things like nose drops. A hypertonic solution contains a higher concentration of salt than your body fluids.
Hypotonic drinks contain fewer particles than body fluid and are absorbed faster than plain water. Lucozade Sport Hydro Active is an example of a hypotonic drink that contains only 1-3% carbohydrates and thus provides less energy than its isotonic equivalent.
