To prepare 1000 mL of a 0.1 mol/L solution of Sodium chloride
Chloride
The chloride ion is the anion Cl⁻. It is formed when the element chlorine gains an electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents. Chloride salts such as sodium chloride are often very soluble in water. It is an essential electrolyte located in all body fluids responsible for maintaining acid/base balance, transmitting nerve impulses and reg…
- Add 11.69 g of NaCl to an appropriate beaker (100 mL beaker in this case).
- Raise the volume to 100 mL with deionized water.
- Add a stir bar to the beaker and leave it on a stir plate until completely dissolved (~1 min).
- Sterile-filter, if desired, and transfer to an appropriately labeled container.
How can I prepare 100 ppm stock solution of Na using NaCl?
Originally Answered: How can I prepare 100 ppm stock solution of Na using NaCl solution? 100 ppm of sodium in one liter would be 0.1 g of Na or 0.1 x 58.443 / 22.98 = 0.254 g of NaCl. This may be tricky to weigh exactly and it would be better to weigh 2.54 g to make one liter at 1000 ppm of Na.
What is the purpose of NaCl stock solution protocol?
NaCl Stock Solution (2.0 M) The purpose of this protocol is to prepare a 2.0 M NaCl stock solution. NaCl, or table salt, is often added to solutions in order to adjust their tonicity (NaCl composes the majority of the ions in PBS, TBS, and similar buffers).
How do you prepare NaCl for reagent preparation?
Raise the volume to 100 mL with deionized water. Add a stir bar to the beaker and leave it on a stir plate until completely dissolved (~1 min). Sterile-filter, if desired, and transfer to an appropriately labeled container. Farhat, Y. “ Reagent Preparation: NaCl (2.0 M).”
What equipment is needed to prepare NaCl?
Normal lab equipment, such as pipettes, serological pipettes, graduated cylinders, beakers, a stir plate, a stir bar, a scale Add 11.69 g of NaCl to an appropriate beaker (100 mL beaker in this case).

How do you prepare a stock solution?
A stock solution is prepared by weighing out an appropriate portion of a pure solid or by measuring out an appropriate volume of a pure liquid, placing it in a suitable flask, and diluting to a known volume. Exactly how one measure's the reagent depends on the desired concentration unit.
Is NaCl a stock solution?
Sodium chloride (NaCl) solution, especially at a 5 M concentration, is a commonly used stock solution for a variety of solutions.
How do you make 1M NaCl stock solution?
The molecular weight of sodium chloride (NaCl) is 58.44, so one gram molecular weight (= 1 mole) is 58.44g. If you dissolve 58.44g of NaCl in a final volume of 1 litre, you have made a 1M NaCl solution.
How can we prepare a stock solution of 50mm NaCl 100ml water?
To make 100 ml of 50 mM stock, 5 mls of 1M NaCl is added to 95 ml of water.
How do you make a 100X stock solution?
To make a typical 100 microMolar (100X) stock concentration of primers, dissolve the primers in a volume of sterile distilled water that is 10X the amount of nmoles in the tube, using microliters of water. This value is printed on the side of the tube.
How do you make a 10X stock solution?
To make 1 L of 10X TBS stock solution, dissolve 24 g Tris and 88 g NaCl in 900 mL of water and then adjust the pH to 7.6 and final volume to 1 L.
How would you prepare 1M solution of NaCl in 100 ml?
= c2/c1) is 0.1M/1M = 1/10. To make 100 ml of 0.1M NaCl, one would pipette 10 ml of stock 1M NaCl into a 100 ml volumetric flask, and bring the total volume to 100 ml with water.
How do you make a 1% solution?
Andrea's Help Sheet on Preparing Solutions.First, know the definition of a % solution: 1% = 1g/100ml.The three steps are:20% = 20g/100ml.3: scale to the final volume by multiplying by 10: 20% = 200g/1000ml.
How would you make a 0.5 M solution of NaCl?
If a different molarity is required, then multiply that number times the molar mass of NaCl. For example, if you wanted a 0.5 M solution, you would use 0.5 x 58.44 g/mol of NaCl in 1 L of solution or 29.22 g of NaCl.
Why are stock solutions prepared?
Stock solutions are used to save preparation time, conserve materials, reduce storage space, and improve the accuracy with which working lower concentration solutions are prepared.
How do you prepare 1 mL of 1 mM NaCl using the NaCl solution you prepared in question 1?
1 Answer. A 1M solution that contains 1liter is prepared by weighing 58.44 grams of NaCl and placing this amount of salt in a 1 Liter volumetric flask and then filling the flask with distiller water to the graduation mark.
How do you make a 10mm NaCl solution?
Normality is a measure of concentration equal to the gram equivalent weight per liter of solution. For making NaCl Solution 10(N), add water to 584.43(g) NaCl till its volume reach to 1(lit).

Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. She has taught science courses at the high school, college, and graduate levels.
Important Points to Remember
Molarity is expressed in terms of liter of solution, not liters of solvent. To prepare a solution, the flask is filled to the mark. In other words, it is incorrect to a 1 liter of water to a mass of sample to prepare a molar solution.
