0,2 g sodium chloride
Sodium chloride is used to prepare the 0,9 % isotonic solution.
Dissolve 500 mg sodium chloride in 1L water.
Sodium chloride is used to prepare by electrolysis (in solution or melted) sodium hydroxide, hydrogen, chlorine, sodium.
The answer is 200 g sodium chloride.
To prepare a 1,5 M sodium chloride solution we need 87,659 g NaCl.
The answer is 0,1648 g NaCl.
A sodium solution of water cannot be made as sodium reacts violently with water to produce sodium hydroxide.
By a slowly evaporation of water from a NaCl solution.
It depends on the volume, if we consider 1 liter of the solution 500 mg of sodium chloride is needed.
Sodium chloride solution is not an indicator.
