1 mg/l = 1ppm
1 g/l = 1000 ppm
NaCl ----------------> Na+ + Cl-
58.5 g NaCl gives 22.989 g Na+
(58.5 / 22.989) = 2.545 g of NaCl is required to give 1 g of Na+
When 2.545 g of NaCl is dissolved in 1 liter water will yield 1000 ppm of Na+ in NaCl solution.

You are provided with a 1000ppm sodium solution describe how you would prepare a volume of 200ml with a concentration of 5ppm sodium in a two step dilution?
To prepare a 200ml solution with a sodium concentration of 5ppm from a 1000ppm stock solution, you will first dilute the stock solution by a factor of 200. So, take 0.2ml of the 1000ppm solution and dilute it to 40ml with water. This will give you a solution with a concentration of 50ppm. Then, take 0.4ml of this 50ppm solution and dilute it to a final volume of 200ml with water to achieve the desired 5ppm sodium concentration.
Is sodium chloride solution a standard solution?
Sodium chloride is a crystalline solid but can be dissolved in water to form a solution.

Preparation of standard solution and standardization of hydrochloric acid Objective : To prepare a standard solution of sodium carbonate and use it to standardize a given solution of dilute hydrochloric acid. Introduction : Anhydrous sodium carbonate is a suitable chemical for preparing a standard solution (as a primary standard). The molarity of the given hydrochloric acid can be found by titrating it against the standard sodium carbonate solution prepared. The equation for the complete neutralization of sodium carbonate with dilute hydrochloric acid is Na2CO3(aq) + 2HCl(aq) → 2NaCl(aq) + CO2(g) + H2O(l) The end-point is marked by using methyl orange as indicator. Chemicals :solid sodium carbonate, 0.1 M hydrochloric acid
Why sodium carbonate is used in preparation of thiosulphate solution?
Sodium carbonate is used in the preparation of thiosulfate solution to help maintain a stable pH level during the reaction. It acts as a buffer to prevent large fluctuations in pH that could affect the reaction rate or yield of the thiosulfate solution. Additionally, sodium carbonate helps to dissolve the thiosulfate salt more effectively in water during the preparation process.
How do you prepare 1000ppm sodium solution from sodium chloride?
To prepare a 1000 ppm sodium solution from sodium chloride, first calculate the molecular weight of sodium chloride (NaCl). Then, dissolve the calculated amount of NaCl in a known volume of water to achieve a final concentration of 1000 ppm (1 mg/L). Make sure to accurately measure the mass of NaCl and volume of water to ensure the desired concentration is reached.
How we standrise sodium carbonate solution?
Titrate it with a standard base.
Why Lithium or potassium metal are not used instead of sodium during the preparation of sodium extract solution why?
While lithium and potassium are also alkali metals like sodium, they are more expensive and less commonly available in comparison to sodium. Sodium, being more abundant and cost-effective, is preferred for the preparation of sodium extract solution. Additionally, the reactivity of lithium and potassium is higher than sodium, making them more challenging to handle in this context.
How can you prepare 1ppb from1000ppm sodium standard?
To prepare a 1 ppb sodium solution from a 1000 ppm sodium standard, you can dilute 1 mL of the 1000 ppm sodium standard with 999 mL (or 999 g) of solvent. This will result in a final solution with a concentration of 1 ppb, as 1 mL is equivalent to 1 mg in this case.
Why is standardization of sodium chloride solution with the help of known silver nitrate solution needed?
Sodium chloride may be used as standard (for example to prepare sodium solutions with known concentration) because is a stable compound.
Why sodium hydroxide is not a suitable regent to prepare a primary standard solution?
Sodium hydroxide is hygroscopic, meaning it easily absorbs moisture from the atmosphere, which can lead to inaccurate concentration measurements. It is also prone to reacting with carbon dioxide in the air, affecting its purity. Additionally, due to its strong caustic nature, it can be hazardous to handle during preparation of primary standard solutions.
Is the standard enthalpy of solution of sodium chloride an intensive property?
Yes, it is an intensive property.
Conclusion of preparation of solution of HCl and NaOH to be standardized?
In the preparation of a solution of HCl and NaOH to be standardized, it is crucial to accurately measure the quantities of the reagents and ensure their purity. The solutions should be mixed thoroughly to ensure homogeneity, and the final solution can then be standardized using a primary standard such as potassium hydrogen phthalate (KHP) for acid or sodium carbonate for base. Conducting titrations afterward with the standardized solution will help determine the exact concentrations of the initial solutions.
