What does an onion cell look like after adding a salt solution NaCl?

This depends on the nature of the NaCl solution...
If it is a Hyper-tonic solution (More concentrated solution than onion cells), water will move by osmosis down it's concentration gradient, from a region of less negative water potential (high Ψ) in the onion cell, to a region of more negative water potential (low Ψ) in the solution through a selectively/partially permeable membrane;
so the onion cell will be plasmolysed and will look "flaccid" (vacuole gets smaller and shrinks).
The vice versa happens with a Hypo-tonic (less concentrated solution than onion cell) NaCl solution;
The onion cell will then look "turgid" (has a large vacuole exerting a pressure on the cytoplasm and pushing it towards the cell's cellwall to make it "tensed".

What will happen if a red blood cell is placed in 50 percent NaCl solution?
A red blood cell, when placed in 50% NaCl solution, will shrink as the water contained in it will be sucked into the surrounding solution doe to the osmotic pressure difference.
What happens when a bacterial cell is placed in a solution containing 5 percent NaCl?
Exo-osmosis of the bacterial cell takes place, the cell plasmolised & cell can die.
How can you make NaOH from sea water and what are the reactions?
Sea water mainly comprising of NaCl is separated and formed into a concentrated solution of NaCl called 'Brine'. Than in a diaphragm cell you add the NaCl (conc) and use Titanium Anode and Steel Cathode. At Anode Cl2 gas is released and Cathode H2 gas is released and the remaining solution is NaOH which is filtered out.
What appearance will red blood cells have when they are placed in 9.0 percent NaCl?
Since a 9% saline solution is hypertonic as compared to the cell, it would crenate (crush or shrink).

What is the purpose of adding iodine solution to the onion cell?
to check the approximatedly amount of starch in it since starch in reaction with iodine a black purple colour is formed
What happen to blood cell in 10 percent NaCL?
A 10% NaCl solution is hypertonic to a blood cell and would cause the cell to shrink, aka crenation.

What will happen if you put onion skin cell into 10 percent sugar solution?
Osmosis takes place. The onion cell will turn flaccid due to the water loss.
Why onion cells 5 percent salt solution hypertonic?
A cell is hypertonic when it has a greater concentration than its environment, but, when a solution is hypertonic, it has a greater concentration than the cell it is being compared to. For example, a 5% salt solution is hypertonic to an onion cell while the onion cell is hypotonic to the solution.The salt concentration of an onion cell must be less than 5% - actually its somewhere between 1.6 and 1.3 percent.This question should not be in genetics, but I don't feel like switching it.
What happens to the protoplasm if immersed on NaCl solution?
protoplasm tends to shrink due to NaCl..causing it to dehydrate and pulling the water out of the cell..
What would most likely happen to a onion cell of it were placed in a liquid with a concentration of solutes?
In a hypotonic environment, an onion cell will fill up with water. Hypotonic refers to a solution that has lower osmotic pressure than the solution you're comparing it to.
Why half of the onion epidermal cell is in darkness under the microscope?
becuse of the lodine solution
What are 3 solutes in a purple onion cell?
one solute is Logols Solution. I think!
What is an istonic solution for red blood cells?
Nothing will happen to a red blood cell in an isotonic solution. An isotonic solution means that the amount of solvent in the solution is the same inside the cell as it is outside the cell. Osmosis occurs, but the water going into the cell equals the water leaving the cell. A red blood cell in a hypotonic solution will burst because more water will go into the cell than the water leaving it. A red blood cell in a hypertonic solution will shrivel up because more water will leave the cell than go into it.
What would happen to red onion cell if sucrose solution added?
In a hypotonic solution like distilled water the onion cell would "swell up" and the cytoplasm expands and water diffuses into the cell
How does sodium chloride cause lysis of red blood cell?
Basically it works like this. Blood contains about .9 % NaCl. If a hypotonic solution say .5% NaCl is introduced, the water from the solution will diffuse through osmosis into the red blood cells until they rupture (lyse). If an isotonic solution of .9%NaCl is introduced, nothing will happen. If a hypertonic solution is introduced say 1.5% NaCl the osmotic pressure will be greatest inside the red blood cell and water will leave the cells and they will shrivel. The cell membrane is for all intents and purposes impermeable to the NaCl so only water will pass through it. The water will flow from a less saline solution to a more saline solution to try to equalize the osmotic pressure.
