TIPS, TRICKS AND INSIGHTS

Making a "Normal" solution. Normality means the number of moles per liter in the solution. Unless you are making an analytical solution, exact measurements and de-ionized water may not be required.

  • Example: we want to make a 0.2N solution of sodium hydroxide. Sodium Hydroxide has one unit of (OH) so this calculation is the same as Molarity.
  • Sodium Hydroxide is 39.997 grams per mole.
  • 0.2 moles of Sodium Hydroxide is 7.9994 grams.
  • Put 7.9994 grams in your container.
  • Add de-ionized water until exactly 1 liter.
  • You now have a 0.2N solution of sodium hydroxide.
