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.

How do you prepare 1000ppm sodium solution from sodium chloride?
A sodium solution of water cannot be made as sodium reacts violently with water to produce sodium hydroxide.
Preparation of 0 38 M sodium acetate solution?
how will you prepare 0.38M sodium acetate solution
Why sodium carbonate is used in preparation of thiosulphate solution?
To ensure the stability of the solution
Is sodium chloride solution a standard solution?
Sodium chloride is a crystalline solid but can be dissolved in water to form a solution.
What is the Frame structure of Serial Line Internet Protocol?
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
How we standrise sodium carbonate solution?
Titrate it with a standard base.
What is the Method of preparation of 3 percent solution of sodium hydroxide?
30 gm of sodium hydroxide desolved in 1 litre distilled water.
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?
you can only use the following glassware 5 10 20 25 and 50ml pipette 50 100 200 or 500ml volumetric flasks
Preparation of 0.1 normal solution of sodium carbonate in 1 liter?
52.5g of Na2CO3 in 1 litre water
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.
What does a sodium hydrogen carbonate indicator do?
Sodium hydrogen carbonate is used as an indicator of pH or as a test for the concentration of carbon dioxide. For the preparation of the solution see the link below.
Is the standard enthalpy of solution of sodium chloride an intensive property?
Yes, it is an intensive property.
