What is the role of NaCl in Nutrient broth?
NaCl is generally added to the nutrient media for maintaining the Osmotic pressure. Maintaining osmotic pressure is important, because, increase or decrease in the osmotic pressure leads to cell burst or death due to the effect of osmosis. So, maintaining the osmotic pressure is done by adding correct amount of NaCl.
What is the osmotic pressure of NaCl?
NaCl--table salt--is typically look at as the solid solute within a solution. The osmotic pressure you need is for the solvent which will need to be calculated I believe. The Van Hoff Factor for NaCl (1.9) is probably what you needed
What is physiodose NaCl 9?
This a saline solution with the concentration of 0,9 g NaCl/100 mL distilled water. This is a isotonic solution; the meaning is that the osmotic pressure of the this solution is equal to the osmotic pressure of the blood serum.
What solutions will give rise to a greater osmotic pressure at equilibrium 3.60 g of nacl in 351.2 ml water or 50.0 g of glucose in 400.8 ml water for NaCl mw 58.5 amu for glucose m?
The greater osmotic pressure will be observed with 3.60 g of NaCl in 351.2 ml of water. This is because NaCl dissociates into two ions (Na+ and Cl-) in solution, contributing more particles that will contribute to osmotic pressure, compared to glucose which does not dissociate.
What is the function of NaCl in LB media?
Sodium is necessary for the osmotic equilibrium.
How does 09 percent NaCl work?
The solution of NaCl with the concentration 0,9 % is considered normal saline; the osmotic pressure is equal to the pressure in the cells.
What is the osmotic pressure of saline?
Osmotic pressure of saline (0.91% NaCl w/v) is arround 0.0085 ATM.The osmotic pressure is 7.58 ATM at 25 °C. P=MRT The molarity of 0.9% NaCl is 0.155M. But it has 2 ions per formula so 0.31 mol/L * 0.082 latm/Kmol * 298K= 7.58 ATM
What is the osmotic pressure of NaCl in H2O?
1 mol/L sodium chloride is equal to 2 osmol/L.
Calculate the isotonic coefficient for NaCl if a 07M of NaCl solution equaled the hemolysis of14M glucose solution?
i = isotonic molar [glucose] / isotonic molar [NaCl] i = 14 M / 7 M = 2 i = isotonic molar [glucose] / isotonic molar [NaCl] i = 14 M / 7 M = 2 i = isotonic molar [glucose] / isotonic molar [NaCl] i = 14 M / 7 M = 2 i = isotonic molar [glucose] / isotonic molar [NaCl] i = 14 M / 7 M = 2
Which has the highest osmotic pressure pure water C6H12O6 NaCl CaCl2?
CaCl2. Because it breaks down into 3 particles , 1 Ca and 2 Cl. "i" for CaCl2 is 3 While NaCl breaks down to only 2 particles Water and C6H12O6 do not break down at all, they remain as single particles.
Which has a lower freezing temperature 0.10 m NaCl or 0.10m glucose?
0.10m NaCl has a lower freezing temperature compared to 0.10m glucose. This is because NaCl dissociates into more particles in solution, causing greater osmotic pressure that lowers the freezing point more than glucose, which does not dissociate.
What term would you use to describe the tonicity of 0.9 percent NACL for red blood cells?
Isotonic. A 0.9% NaCl solution is isotonic to red blood cells, meaning it has the same osmotic pressure as the cytoplasm of the cells, and therefore will not cause them to shrink or swell.
