BSS (ophthalmic irrigation solution) (produced by Alcon) . Composition per 1 mL: sodium chloride (NaCl) 6.4 mg, potassium chloride (KCl) 0.75 mg, calcium chloride dihydrate (CaCl 2 ·2H 2 O) 0.48 mg, magnesium chloride hexahydrate (MgCl 2 •6H 2 O) 0.3 mg, sodium acetate trihydrate (C 2 H 3 NaO 2 ·3H 2 O) 3.9 mg, sodium citrate dihydrate (C 6 H 5 Na 3 O 7 ·2H 2 O) 1.7 mg, sodium hydroxide ...
Mg 0.1 0.015 All others ... All of the mass of the trace elements put together (less than 10 grams for a human body) do not add up to the body mass of magnesium, the ...
The solution is 9 grams of sodium chloride (NaCl) dissolved in water, to a total volume of 1000 ml (weight per unit volume). The mass of 1 millilitre of normal saline is 1.0046 grams at 22 °C. [12] [13] The molecular weight of sodium chloride is approximately 58.4 grams per mole, so 58.4 grams of sodium chloride equals 1 mole. Since normal ...
In 2013, compounds of sodium and chloride of different stoichiometries have been discovered; five new compounds were predicted (e.g., Na 3 Cl, Na 2 Cl, Na 3 Cl 2, NaCl 3, and NaCl 7). The existence of some of them has been experimentally confirmed at high pressures and other conditions: cubic and orthorhombic NaCl 3 , two-dimensional metallic ...
Seawater has a salinity of roughly 35,000 ppm, equivalent to 35 grams of salt per one liter (or kilogram) of water. The saturation level is only nominally dependent on the temperature of the water. [1] At 20 °C (68 °F) one liter of water can dissolve about 357 grams of salt, a concentration of 26.3 percent by weight (% w/w). At 100 °C (212 ...
Hanks' salts is a collective group of salts rich in bicarbonate ions, formulated in 1940 by the microbiologist John H. Hanks. [1] Typically, they are used as a buffer system in cell culture media and aid in maintaining the optimum physiological pH (roughly 7.0–7.4) for cellular growth.
Thus, for every 1 mole of NaCl in solution, there are 2 osmoles of solute particles (i.e., a 1 mol/L NaCl solution is a 2 osmol/L NaCl solution). Both sodium and chloride ions affect the osmotic pressure of the solution. [2] Another example is magnesium chloride (MgCl 2), which dissociates into Mg 2+ and 2Cl − ions.
A river or lake water with a salinity of around 70 mg/L will typically have a specific conductivity at 25 °C of between 80 and 130 μS/cm. The actual ratio depends on the ions present. [ 14 ] The actual conductivity usually changes by about 2% per degree Celsius, so the measured conductivity at 5 °C might only be in the range of 50–80 μS/cm.
