If you think to an isotonic solution the concentration is 0,9 g NaCl/100 g solution.
The solution of NaCl with the concentration 0,9 % is considered normal saline; the osmotic pressure is equal to the pressure in the cells.
normal saline is 0.85%w/v NaCl whlist physiological saline is 0.90% w/v NaCl.
normal saline is 0.85%w/v NaCl whlist physiological saline is 0.90% w/v NaCl.
Saline is nothing more than salt water. Salt is NaCl. Normal saline is a 0.9% solution of NaCl in H2O.
It is saline that has twice the concentration of salt as normal saline. Normal saline is 0.9% NaCl, so twice normal is 1.8% NaCl. Now I have a question. Is this ever given to patients?
Not exactly. Saline solution is sterilized and is a dilution of sodium chloride (NaCl) - meaning that the NaCl is dissolved in deionized water. The solution is 9 grams of sodium chloride (NaCl) dissolved in 1 liter of water.
it is hypotonicQuoting from someone else's reply to this question What_is_an_example_of_a_hypotonic_solution,"0.45% NaCl (half-normal saline solution); since normal saline is 0.9% NaCl, any solution less than 9% is hypotonic".Doesn't this mean that 10% is hypertonic?
9% NaCl is a hypertonic saline solution. Red blood cells will appear to shrink as they lose water out of the cell membrane and into the saline solution.
Gram percent is the number of grams of a solute per 100 grams of a solution. For example, if a solution of NaCl and water was said to have a 0.02g% of NaCl, this would mean that for 100g of saline solution, 0.02 of those grams are salt. Since 1L of water weighs 1kg (at normal conditions), there would be .2g of NaCl in 1L of a 0.02g% NaCl solution.
NaCl (ag)
Saline. Sometimes referred to as normal saline or 0.9% NaCl.
Solid NaCl is not an electrolyte; the saline solution or the molten NaCl are electrolytes.
