5% NaCl solution is unusually high. And because all living organisms seek to maintain an isotonic balance with their environment,osmotic diffusion will occur in order to re-establish this balance.Hence,there will be a diffusion down the gradient i.e. from the medium containing the NaCl solution,into the bacterial cell which has solutes dissolved in it but insufficient to even out this balance.The end result will then be lysis or bursting of the bacterial cell,as it gorges in the NaCl to maintain equilibrium.

Why is NSS or 0.85 percent NaCl solution used in emulsifying the bacterial smear?
0.85% nacl sol or normal saline solution is used as it is an isotonic solution which will emmulsify bacterial cells and dont cause any injury ( injury due to osmotic gradient in which cell can shrink or swell/burst ). solution upto 0.98% can be used.
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 parts of a bacterial cell does sodium hypochlorite bleach attack?
Lipids of the cell membrane. no - it's a general strong oxidizing agent
Is chlorine mined?
Chlorine itslf is not mined. The materials used to produce chlorine (NaCl) is mined. Chlorine is produced by electrolytic reaction of a chloride solution (e.g. NaCl) in a process involving a diaphragm cell or a mercury cell. The mercury cell process has been largely discontinued because of its associated loss of mercury to the environment.
Edge length of NaCl unit cell?
Roughly 0.564nm. It takes on a face-centered cubic structure.
What happens when a bacterial cell is placed in 10 percent Nacl with penicillin?
The cell will plasmolyze.
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.
What will happen if a bacterial cell is placed in distilled water with lysozyme?
lysozyme will diffuse in to the cell
What will happen to freshwater bacterial cell that is placed in salt water?
Water leaves the cell, causing the cell to shrink.
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 will happen to a freshwater bacterial cell that is placed in salt water Will water enter or leave the cell?
It will leave the cell, causing the cell to shrink.
What would happen if freshwater bacterial cells are placed in salt water?
water leaves the cell causeing the cell to shrink.
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 happens to a cell when is placed in a hypersonic solution?
The cell expands/gets bigger.
What happens first when a phage infects a bacterial cell and is going to enter a lysogenic cycle?
it becomes a part of the bacterial DNA and it can be replicated into the daughter cells. this cycle doesn't harm the bacterial cell but it can change into the lysis cycle and kill the host cell
What happens when a cell is placed in an isotonic solution?
Nothing. There would be no gradient between the cell and the solution.
What happens when water moves out of a cell if the cell is placed in a what solution?
Hypotonic Solution
