1.Weigh 58,44 g ultrapure NaCl dried at 110 0C for 30 min.
2. Transfer NaCl in a clean 1 L volumetric flask using a funnel. 3. Wash the funnel with 0,9 L demineralized water.
4. Put the flask in a thermostat and maintain 30 min at 20 0C.
5. Add demineralized water up to the mark.
6. Stir vigorously and transfer in a clean bottle with stopper.
7. Add a label with necessary information.
sodium plus chlorine yields sodium chloride
Sodium chloride is the result of this reaction: NaOH + HCl = NaCl + H2O
Sodium chloride is used to prepare the 0,9 % isotonic solution.
0.056g
Sodium hydroxide solution will be on the top.
Adding hydrochloric acid.
Sodium chloride is NaCl. Sulfuric acid is H2SO4.
The answer is 0,1648 g NaCl.
Chlorine gas. Cl2
The salt used to prepare a mummy is sodium carbonate not sodium chloride.
Sodium is separated from sodium chloride by electrolysis.
By a slowly evaporation of water from a NaCl solution.
